To pile on to the suggestions;

1. Make the hitpoints of the castle relatively small. Since the game does lend itself to one player getting dominance relatively quickly, you don't want to drag out the battle when it's clear who's going to win.
2. A game like this is all about having a good rock-paper-scissors system. For example mounted beats archers, who beat infantry, who beat mounted. For this to work, you need to force players to chose between three or more options, instead of sending out all unit types at once. One way to do may be to have a high unit cost, so players simply can't afford to send all unit types.
3. Along the lines of point 2, provide buffs to having a lot of the same unit type. This fights the natural advantage a balanced army has. This can be in the form of another unit that helps all units of the same class. For example a general that leads your infantry, or an apprentice that powers up your mages.
4. Make sure every unit has a weakness. If someone gets an brief advantage by spamming one unit type, it should be easy to counter that the next round (but of course a better player will anticipate the counter, and spam units to counter the counter).
5. Make each faction feel unique by giving each an advantage for a particular player strategy.
6. In a game like this you have two metrics of how well you're doing: the number and streangth of units in play, and the position of the line of scrimmage. Try to make it possible for these not to match. For example, have units who knock back the enemy without dealing a lot of damage, and have slow moving powerful units.
7. Make sure the play area is wide enough so that as a player is loosing the line of scrimmage, they gain the benefit of reacting better because they can see which enemy's units are on the way.
8. Area attacks are a counter for large numbers of units. Percent of max hp attacks are a counter to singular strong units. Include both.
9. Make sure you have a test mechanism that tests the balance of each strategy and faction. Game-play telemetry is useful too, if possible.

1. That would be one possibility, yet I think it would be better to find a way for the player to successfully defend the castle against even a big army and to launch a counter attack. It is true, that during one match (/game) in one battle, there, usually, is one clear winner (the stronger army destroys all enemies), however, the goal is, that there are multiple battles during one game. The player should still have the possibility to destroy the army of the enemy after some time. Possibly, because of tactical elements, such as 'rock, paper, scissor'-like unit types or, for example, area attacks
2. I agree and have one more comment, which I will add to point 3
3. this is a great point. The player should have an advantage by having many units of the same type, otherwise he will simply build a very balanced army. Maybe the following: The main attribute of the unit (e.g. health for tanks, damage for mages, range for rangers) is boosted, based on the amount of units of that type. For example, more tanks results in even more health and more mages results in even more damage. This is a really good idea.
4. Similar to point 2 and 3. If we use the rock, paper, scissor system and boost groups of the same unit type, this would apply
5. Would be ideal and we should definitely invest time into this topic. Probably not very easy, because there are over 20 tribes, yet, I guess, it would be okay, if there are some overlaps
6. Already the case, to a certain degree: Units can have armor (makes immune to mage/ranger attacks), which makes those units very slow
7. Yeah, although there needs to be a good balance. Otherwise, it might be frustrating: If you build a good army, which finally arrives at the enemy, but the enemy builds an effective counter (he has a lot of time to react, because he knows exactly who is coming to him) and you do not have any ways of helping your army, because support would take too much time to arrive, this would be frustrating
8. Good idea. Especially the area attacks. I am not sure about the ‘Percent of max hp attacks’, because they might be too op against Heros and, otherwise, useless against everyone else. Possibly a viable special attack with a big cooldown
9. Yes, I agree. We already set up Python tooling, which can automatically simulate matches and print out statistics of the resulting matches. The game simulation depends on the AI, though. If we succeed, we will use reinforcement learning to train a good AI

You say you want to avoid one player holding attacks until he can overwhelm the other. So the gameplay would be about sequence, the player tries to produce units in the right sequence, countering enemy units and sending their heavy hitters at the right moment to destroy enemy castle. King Mir had very good suggestions to implement for this gameplay.

Don't give armor to shooters and mages or they will steamroll everything. Also King Mir mentioned Area attacks to counter numbers, then you need a unit resistant to area attacks to counter the former.

attacks of the units can destroy each other (e.g. fireball destroys flying axe or arrow destroys boomerang), based on the strength of the corresponding attacks

The problem of 1 Dimension and missiles collidig whith each other is that once a formation is able to overcome the enemy firepower it will destroy everything behind, and it's unlikely the enemy will be able to amass enough firepower to tip the balance again. I suggest to rethink that mechanic implementing King Mir ideas about rock, paper, scissors.

I like the idea of a wide space between castles so the batlle moves back and forth. Maybe add a mechanic to send a builder to a specific point and build a specific building there.

The game is intended for both. In the beginning, human vs AI. Later, we want to support human vs human too. The game, already, is deterministic (if the same hardware is used) and human vs human should be possible, but probably is still a lot of work to implement.

Yeah, the AI should be really good, which is why we are trying to train it with reinforcement learning. Additionally, we already wrote some balancing helpers: the money, which the AI gets, is multiplied with a balancing factor. This balancing factor depends on the worth of assets (money/units/building) the AI has in comparison to the enemy. The AI can get up to 1.5 times as much money, as usual, if it is very poor, compared to the enemy.

Yep, the game is about sequences of units and battles.

Regarding the 1 Dimension issue: this is, in general, correct, yet via mechanisms, such as a rock, paper, scissors system and the other ideas discussed above (e.g. area attacks or special attacks of the heros, with a big cooldown) it should be possible for a player to turn the game around to their advantage.

The possibility of building buildings at any position is something we have to test out. Maybe it is really good, maybe it is overpowered.

You should probably do both. Have a difficulty scale for AI buffs, and do your best to make a smart AI.

merkutsam said:

A unit resistant to area attacks is simply a unit with high hp or armor. The trade off is lots of weak units, or one strong unit.

Right now, we have the unit types Hero, Tank, Melee, Ranger, Mage. The tank, for example, has a lot of health, but only a short range attack. Additionally, units can wear armor, which makes them immune to attacks of rangers/mages (long range attacks). Units with armor are very slow.

Ok, So melee is cheep and has large numbers, and is strong against rangers. A mage can have an area attack to be good against that. A tank has armor, so counters a mage, and also the low attack of melee. Then maybe your hero deals damage proportional to max health, so counters both mages and tanks. And a ranger is also cheap, but has a bonus against tanks. There you go, 5 way RPS system.

For example.

Then give each faction a special unit or ability that boosts one or 2 of those 5 unit types.

Another thing, you mentioned that you have a healing fountain. I actually think you should avoid having abilities that heal units, because they keep units on the field. You might still be able to make it work if you favor certain unit types. For example, heal hp at a fixed number per second, so that it favors cheep units, and make this a faction special ability, for, say, snowmen.

Yeah, the healing fountain should have a very limited amount of heal hp per second.

Regarding the rock, paper scissor topic: right now, I consider the following system:

• Tank simply has high health but has no other big advantage. Also it has a low range
• Melee is rather cheap, deals a decent amount of damage, has a low range, has medium health and is very effective against buildings (which have a lot of health and are, otherwise, hard to destroy). The more melee units are close together, the more damage they deal
• Ranger has a high range, low health, medium damage and is effective against tanks. The more ranger units are close together, the more range they have (yet not too much, otherwise it would be very op)
• Mage has a high range, very low health and high damage. The more mages are close together, the more damage they deal

Re: ‘Percent of max hp attacks’, because they might be too op against Heros and, otherwise, useless against everyone else. This is kind of the point; they're a counter to high hp units, just like weak area attacks are only really effective against many units.

So those bonuses for having many of the same unit in play are great.

But I'm not seeing much of a rps system between those 4 unit types. If the enemy spams tanks, it's clear I should spam rangers. What if the enemy spams melee? Are mages area attacks? if so that would help. What if they spam rangers?

I suggest mages beat melee, give melee a buff against rangers, rangers beat tanks, and tanks would be good against mages because of the mages low individual attack. Melee vs tanks would be equal (per dollar), and so would mages vs rangers. But a problem with this is where do heros fit it? they're basically tanks if they have high hp. You could make hero mages and hero rangers to some extent, but not hero melee, since those have the most strength in numbers.

I think an odd number of base unit types may be better, so there's no balanced fights.

One thing to keep in mind is there are side effects speed beyond the fact that it counters ranged units; a fast unit can get to the front quicker. this would make them worse for staring out, and better as support later. That automatic “play later” attribute is probably not very desirable, because it makes the start of play more predictable.

Since you have buildings, you should definitely add slow moving siege. Specifically battering rams and seige towers. That doesn't add to the RPS, but it does add an importance to timing; you want to send in siege precisely timed with when your other units reach the enemy walls.

Since you have ranged siege, be sure to provide at least three variants of that too: splash attacks, frequent single unit attacks, and high damage slow attacks. For this you probably want your stronger units to be completely immune to splash attacks, so that it doesn't automatically become the best counter for multiple units of any type. Unlike units, ranged siege isn't going to be destroyed easily so the balance around it is a bit different.

I think your idea to have a reinforcement learning AI has a problem: at the same time as you work on the AI, you want to work on balancing the game. So if your AI discovers a preferred strategy, instead of making the AI use that strategy, it may be better to change the game so the strategy is less effective.

Or a building like a fortification to shelter units inside. Nevermind, probably buildings aren't a good idea.

Personally I don't like the concept of tanks with many hitpoints. I prefer different types of damage and defense.

To make the whole rps topic a little easier to understand and talk about, I have created diagrams (I am sorry for the low resolution; the arrows point from the effective unit type towards the weaker unit type).

I like this idea, in general, yet, there is one point, which I have difficulties with: How can we, logically, explain to the player, that Rangers are effective against Tanks but weak against Melee? Tanks should be known for wearing the heaviest and strongest armor. Arrows and other rather “light" attacks should not be effective against Tanks if they are weak against Melee, I think.

What about the following alternative? It is similar to your idea and based on your idea.

Instead of Tanks being completely immune to Ranger attacks, it could also be, that they take just very little damage.

King Mir said:

Putting each Hero into one of the different unit classes is a good idea. Could you elaborate on why you think, Melee Heroes would be a bad idea? They could be simply either a Mage/Ranger(/Melee) but with extreme stats.

King Mir said:

Sounds reasonable, but I do not really want to remove one of my classes and adding one would not be suitable either.

What about the following rps-system?:

That automatic “play later” attribute is probably not very desirable, because it makes the start of play more predictable.

Right now, speed of units is handled the following way: Units of the same team form a formation anyways (e.g. take a slot in an invisible formation entity and try to stay on their proper position within the formation). This formation moves with the speed of the slowest unit. Therefore, if you would start with some slow and a few fast units, the formation would move slowly and the fast units would adapt. Only when the fast units are not in a slow formation they move fast. The disadvantage of fast units is that they take up more space, since they use a mount (e.g. horse, wolf, lion) which has a bigger width than usual units.

This is a good idea and could be great against enemy buildings. We will definitely play around with the concept of movable siege machines.

Yep, the AI can be used to discover weak spots and to balance the game. Fortunately, within one minute over 30 complete matches can be simulted, currently. This way, it should be rather easy to re-train the AI many times.

I guess, both have advantages and disadvantages. It can be frustrating if you have no way of protecting your precious unit (e.g. mages with low hit points). Of course, if one decides to go with tanks, those should have weak spots too (e.g. they move slowly and have a low range or are weak against magic attacks). We have made experiments with different attack types and defenses too. We tried the attack classes “Normal” (Melee, Tank), “Light” (Ranger) and “Magic” (Mage) and implemented two types of armor: “Anti Magic” and “Anti Light”. If units of any class can have that armor, this quickly makes everything more complex and, for example, weak spots of a unit class could be negated with the corresponding armor, quickly making a unit overpowered.

@undefined is ther a vacancy for music composer?

We are already in contact with a music composer, however, if we should not agree on working together, I will come back to you ?

I prefer different types of damage and defense.

I mean instead of tanks based on hit points, I prefer them based on good defense against the normal attack but vulnerable to another attack. Ex: infantry with armor and shields is a good tank against arrows, but less effective in melee than pikes. While pikes are better in melee but vulnerable to arrows. Here you have two different melee units, each one with different strengths and weaknesses. I like to base design on reality as much as possible. If you base tanks on hitpoints it needs a counter based on percentage of health which is another unrealistic design. It can be a good game but I prefer the other way.

1. Your second RPS diagram looks fine. Make it so a tank can kill a melee unit in an integer number of hits exactly, to balance them.
2. The problem with a melee hero, is that the strength of melee is numbers. If you have a more expensive melee unit that's harder to kill, that starts to look like a tank. You might be able to have units that buff melee, but they'd need to have low hp. I guess you could still have a tank that buffs melee, balanced by a melee unit that buffs tanks, like a week support unit.
3. Speaking of support units, they can encourage specialization in one unit type is to have support units that boost only that unit type. That's probably a better mechanic over all than just “I have lots of mages so my mages are stronger”.
4. One advantage that cheap weak troops generally have is that you can ramp them up slower. So you might start with a tank, expect the enemy to counter with mages, then instead of sending a tanks cost of melee units together, you can start sending units as soon as you can afford a single one. Because of this, I do like the idea of not making melee part of the main rps loop. However, just making rangers be the only thing that's good against them encourages a strategy of using a lot of melee. What you can instead do everyone equally good against melee. That means no area attacks by your main three.
5. Making melee week against everyone, and having heroes is also nice because then you have three tiers of units, with three tiers of cost. You could even make this another RPS layer, if you make melee good against heroes.
6. Making melee good against buildings seems a bit strange to me from a realism perspective, unless you give them a special anti-building ability, like sapping underground or explosives. Plus there are more realistic anti-siege weapons.
7. The formation system sounds good, but that only makes sense for the front, not for units trying to reach the front. So fast units still have an advantage reaching the front. So you'd want to make them a tad weaker to compensate.
8. Yeah damage types are great, but you'd need to increase the total number of unit types to make it work. So if you're keeping the unit numbers small, then I agree you should keep it out.
9. I don't agree that percentage of hit points are a particularly unrealistic mechanic. It's basically a way to represent a unit that overcomes armor. To such a unit, an unarmored foot soldier or a fully clad knight look like they take the same amount of hits. It's suitable for a unit that deals blunt damage.
10. If you don't have area attacks to counter melee, you can still have attacks that target a fixed multiple of units: double attacks, and triple attacks.

I get your point and this is, for sure, something worth to consider. If we would, for example, go with Tanks that take only very little damage from attacks of Rangers, that would be an example of this design paradigm.

1. Thanks for the hint regarding balancing melee und tank units
2. I'll write a separate section about our thoughts regarding heroes in the bottom
3. We consider the following solution regarding “advantage when you have many units of the same type”: When the player has 3 units of a kind in his formation, a support unit (similar look, but carrying a banner which displays the unit class, e.g. ranger, mage or melee) is automatically spawned and will join the units. It will stay alive, even if the 3 units are killed, until enemies kill this support unit. If the player should have 6 units of a kind, a second support unit is automatically spawned. The support units boost all units of the same class of the player
4. Yeah, all unit classes would be equally good against melee, except ranger who would be naturally effective against melee due to their long range (and their cooldown is not as high as the mage cooldown)
5. Making melee strong against heroes is a good idea
6. I agree and siege machines are cool anyways (and add this additional timing aspect)
7. Already the case: only the units on the front form a formation (which adapts to the speed of the slowest unit) and other units walk on their own
8. I'll comment on this one down below.
9. That would be one way to explain it. Additionally, through an armor system (e.g. no/medium/strong armor against regular attacks or against magic attacks; the damage dealt to a unit would be attack damage minus armor value) this could be realized too: an attack that ignores armor would have a similar effect
10. This is what we are probably going to do

Now, there a few more open topics:

Heroes

Because of the formation system, units choose a position in the 1d army formation, which is suitable for their unit class. A tank will be in the front, next will be melee, ranger, mage. Most enemy attacks target the front unit of the formation. Assuming we keep it this way (an alternative would be just keeping the order in which units are built), it might be overpowered, if a Hero would choose a position in the back.

Why do I mention this?

We could put heroes into one of the unit classes (mage, ranger, possibly melee). If we do this, it would be reasonable if a mage hero would choose a slot in the back, have a huge amount of damage and rather low health (for a hero). Due to the hero having a slot in the back, if it would be protected with tanks in the front, it could deal huge amounts of damage, without taking any damage itself (position in back). Of course, this needs to be playtested, but I feel like this could be overpowered.

An alternative would be putting all heroes in the front of the formation, however that does not feel right, if we decide to go with mage or ranger Heroes, instead of just one tank-like hero class.

Unit speed and buildings

Currently, we have the “attacks destroy each other" option activated (e.g. an axe could destroy an arrow or a fireball a spear), I have talked about this in a previous post. Because of that, the player wants to have an army with as much firepower as possible. Due to that, it is actually positive for the player to have an army, which moves slowly. Walls, that block the army, are welcome, because they slow the army down, giving it more time to grow bigger and stronger. This defeats the purpose of the wall. If the health of buildings would be increased and only a few special siege machines can take buildings down quickly, it would increase this effect even more.

I have not played any game of this kind yet, which used buildings, such as walls. Maybe, because they are really difficult from a game design perspective (chances are that there are such games, which I just do not know). If the “attacks destroy each other" option is deactivated, the effect is not as big (but still exists). I like that option though, because, at least without a proper RPS unit class design, the game felt boring without this option and feels fun with the option (but is harder to balance).

Many different unit types

We have talked a lot about unit classes already (e.g. hero, tank, melee, ranger, mage). Every unit is in one of those classes. However, this does not mean, that there are only 5 unit types: Every single faction/tribe has a unique set of 5 unit types. Examples: the goblin tribe has a goblin boss, a goblin tank, etc. The dwarf tribe has a dwarf boss, a dwarf tank, etc. All those individual unit types are based on the 5 main unit classes, yet they have a few minor differences, such as

• their attack (e.g. golden spear vs mad boomerang vs god axe)
• mount / no mount
• rarity (common, rare, epic, legendary). The rare a unit type is, the higher the stats are but the more expensive it is
• optionally vampire effect (regain some health via damaging enemies)
• a few more differences (for example higher attack rate but lower damage)

My main goal is, to balance the 5 unit classes. The individual unit types should feel a little bit different too, but I am fine with them having just minor differences. I understand, that it is, basically, not managable, to create over 50 unique, well-balanced unit types.

After having put some more time into playtesting and balancing the 5 unit classes, I will think about the possibility to introduce different armor levels (as mentioned in my response to point 9).

Btw.: I really appreciate your time and your help ? Thank you!

Only if all units have the same amount of hit points. If a mage has less points, or a cavalry has more points, then that counter-armor unit will do it worse or better than a normal attack against those units.

@logende

I've been thinking in your game development. I'm guessing so I may be wrong.

First the game was about sequence, unit X beat unit Y, then unit Z beats unit X, then unit Y beats unit Z, and the full circle X beats Y.

This was a waste if an expensive unit beats another one only to be defeated by a cheap one. So you added a formation mechanic. Now units in the front protect weak and expensive units in the back.

But this was a constant meat grinder. Front line units wiped out, and new replacements sent non stop. So you added the missiles cancel each other mechanic.

Now both formations fight as a whole, every unit adding its attack to the struggle until one formation's firepower overcomes the other's. Once this happens, the other formation is wiped out and this is pretty much game over.

In the end what you have been saying is that you prefer a more complex gameplay, one army defeating the other combined army as a whole, not piece meal. Probably not what you want but here you have a few ideas.

• Formations may fight in an abstract way calculating the different combined attacks and defenses, and taking a percentage of their units health, and they may recover health when not in combat.
• Formations don't need to be destroyed everytime they are defeated. They may fall back to their defensive positions if they are losing.
• Formations may advance and retreat, may entrench and fortify, may besiege and assault.
• Formations may fight better in their own lands, and worse in enemy lands
• Formations may change their composition, retiring some units and adding others.
• Formations may apply different tactics for different situations.
• Support units may add different capabilities to formations. Workers, engines, cavalry, spies and counter spies
• Ranged units may have different attacks. Bowmen bombard formation with weak area attack. Crossbowmen like snipers against expensive units. Musketeers piercing attacks anti armor
• Heroes don't need to be combat units, they may be characters leading a formation with different capabilities derived from their traits.
• Mages don't need to be damage dealers, they may be support. They may add buffs and debuffs to attacks and defenses, they may increase healing rate or movement
• Economy may be based on maintenance instead of a fixed # gold per time. One player can maintain a given amount of units. If he uses more expensive units he will have less gold for other units.
