This has 2 problems. It relys on micromanegement and detailed ship manipulation during combat which is not usable in larger/mid scale battles (imagine positioning 20 destroyers so they all show their stronger side to the enemy and repeat it each turn).

Not a problem if the 20 destroyers are manipulated in one stack, like in the first Master of Orion where it was normal to fight with a thousand small ships in one battle.
If you have not played MOO, you really should. For one, it has a nice planet management UI approach - MOO2 was a step backward in that.

First, an assumption, the fun comes first, realism only if it does not interfere with fun and does not make the game too complex. I understand not everyone make games with this assumption in mind, but if possible I would prefer such assumption in this topic since that's the kind of game I want this information for (but if you can't, that's OK ).

In my opinion, the best way to go would be to have well thought out and named slot types(armor, extensions, weapons, electronics and so on) and then give X amount of these slots on different ships. All of the fittables would have requirements for energy, volume and so on while keeping it realistic.

I don't think slots and energy works well together. If you are making a slot based design, the imperative is to use all slots available (otherwise the designed ship is not optimal). For example if you are making a small ship with 6 slots (2x weapon slots, 1x engine slot, 1x reactor slot, 1x armour slot, 1x sensor/electronics slot) and you have 2 types of components per slot (early game) you are highly limited how you assign these if you need to track energy consumption. You might simply end up with only 1 reasonable combination of components since the energy consumption requirements dictated so.
I would say energy is not compatible with slots at all. It makes already heavily restricted slots (which are type restricted already) even more restricted.
On the other hand, if we use space/weight system the energy should fit fine (since we can simply add unlimited number of armour which does not use energy until we fill the whole hull space). In space/weight system additional restrictions (like energy/crew requirements) are much easier to deal with by the player since you can always mindlessly add a bunch of low tonnage components to fill the rest of the hull once all your main componets are there.

I would risk making a theory that slots works only if there are no additional requirements/limitations present...

Another interesting thing, I noticed in some games a fake slot system. Look here: http://www.dotemu.com/sites/default/files/starfury_1_0.jpg this ship has slots which are basicly empty, it also has tonnage. It seems that the bottleneck here is always the tonnage, not slots. What is the point of slots there then? It feels to me as if the slots there were purely decorative thing without any gameplay purpose...

I think no one mentioned it, one of the best 4x games (at least that i heard of) is Aurora, whatever you do, terraforming, bulding spaceships, building defenses, bulding your race, gets an incredible detail, you can set the frequency of the laser you shoot so it can destroy different things more effectively, if you want to make a space-based 4x, i reccomend you look at it, or at least it's wiki, you could get a lot of ideas from it.

Interesting one, thanks. But it took me 5 minute to find the download for this (not even on the first page of google) also I never heard of it even though I'm a hardcore 4x player. From a marketing point of view this game is a failure. I'm not sure if I should steal any ideas any from such unpopular game

[/quote]Yes... Stacking would solve the problem of it being unmanagable. But it kind of defeats the purpose, the point was to make it so separate components on each ship can be damaged an destroyed so you have to carefully place armours and systems. But with stacking you can't make separate damage to each component, since it works as a stack (X units left, can't display a huge page with detailed list of all ships in a stack and the damage to all their components). Partial damage can't work with stacks and detailed ship manipulation works only if you have few ships/stacks to manage and you can have few ships to manage only if you have stacks So it's kinds of is a vicious cycle.
Plus, I'm not sure I would want to base my decision if I want stacks in a game just on ship design requirements... I would prefer a shipdesign system which works for both.

I guess it really comes down to how complicated you want the fitting to be. I usually prefer complicated gameplay and thats why probably my suggestions are complicated. As for using all the slots or not: each module could also have a drawback, the main one could be added mass to ship and the secondary could be something related to the module itself(adding weapons means you need X amount of bigger crew and so on) so there actually is something to gain if you do not fit some module to the ship.

As for the energy, there could be different rails of energy available to module slot types. For example, big rails with a lot of energy to electronics and auxillary systems and little to none to armor.

I can brainstorm long walls of text on the topic, but not sure how well it all fits to 4X and the game you are designing.

I know Aurora is not known, but is basically the same case as Dwarf Fortress, a lone developer without much publicity making his game.

I'm not saying you have to make a clone of it, but check the features and the inmense detail the game gives, and then, if you like something, you can implement it in a simpler way.

Yes, the game is not well known, but that doesn't mean it isn't good.

There are other reasons to carefully place armors and systems besides individual component damage. Armor/shields/ECM could prevent incoming damage only from specific parts of the ship and the player could choose to skimp on them for some parts, then maneuver to minimize exposure of those parts to the enemy. And some weapon systems could require the player to maneuver the ship to get line of sight between the weapon and enemy, while others such as missile launchers might work even while bolted on the opposite side of the ship from enemy direction.

While I prefer it to be more in the synch with the kind of game I'm making any feedback is better than none As long as it is related to 4x spaceship design I would be delighted to read it.

Yup, I checked it already. Even if not for gamedesign reasons I would be unable to resist as a fan of 4x games Unforutunatelly, their spaceship design system is very simple (only tonnage) so I can't steal much from it in this regard.



I was thinking, I approached the issue the wrong way. It's not about space vs slots. Actually, general slots and space system are identical (if you have 10 slots and each can hold 1 component and you can put any combination of these you could end up with 10 lasers; in case of tonnage system if your ship can hold 100 tonnes and each componet weight is 10 tonnes you could end up with 10 lasers). The whole purpose of slots is for them to be specific (like weapon slot, engine slot, etc). So, it is all about restrictions (slots are a way of saying that 20% of your ship has to be weapons). And restrictions can be done other ways than slots (for example energy consumption system).

The key is to use a good combination of restriction systems (also that's why the energy system felt broken to me in combination with slots, these both are basicly restriction systems and were doing the same thing). I would also say, that for as restrictive system as slots we probaly should not use any additional restrictions; but if we use lighter restriction system (like tonnage) it is probably OK to add additional restrictions (like energy consumption, crew, etc).

What you think? Is my way of thinking correct here? Any examples of games that did it other way and were good?

The MOO2 system which you quoted as a positive example has both restriction types. Drive and armor slots must be occupied, computer and shield slots are optional, but anything you put into them affects space which limits the total amount of weapons and other stuff you may put in.
One noteworthy thing about the system is that it is not always worth it to fill all the available space, because any stuff you put in also increases the build cost.

Personally I never liked slot based systems they always seemed either useless if you never filled them all or overly restrictive when they forced you down a certain path.

One of the advantages of the tonnage system is when it’s tied into the R&D so that you get miniaturization and increased hull space. So while you lasers start a size 10 they can eventually be reduced down to size 1. What might be interesting is if you’re R&D system was divided into applied and theoretical sciences so you could choose whether to invest heavily in a new kind of energy weapon or modifications your existing systems.

The fields you could study to improve a laser might be the following:
· Miniaturization - 10 levels – each reduces size by 10%
· Efficiency – 10 levels – each increases damage by 25%
· Power Consumption – 10 levels - each reduces power consumption by 10%
· Armor Penetration - 10 levels

A proto type laser might due 1 damage require 10 space and consume 10 energy per shot. While the maxed out laser would due 2.5 damage ignore 10 points of armor, take 1 space and consume 1 energy per shot. This would mean it does 25 damage for the same cost as the prototype laser. But after that you can’t do any better until you research fusion beams and start developing a new kind of energy weapon. This gives an interesting dynamic of getting the player choose between long term advantage or short term gains.

I do also like the module type system I’ve seen some where once where you fix the weapons and components to parts of the ship and it’s possible to destroy them in battle. That way if the enemy capital ship has their primary weapon mounted on top then it possible to concentrate fire there and destroy it.

Well GSB has the best slot system. Aside from some slots not being weapon slots you can put anything anywhere and put non weapons in weapon slots.

GalCiv had the most customizable system ever, and an RD thing where you could do miniaturization and such. You could load all sorts of crazy designs and have like 50 engines or 50 black hole cannons and such.

I'd go another route and take a look at BattleMech-like games. I enjoyed Titans of Steel a lot some years ago. It has battle robot (equivalent to ships in space combat) that could be customized a lot. There were slots that take armor, weapons and auxiliary systems. All slots take individual damage and armor in that slots protects the body part. Also there is a maximum weight AND there is energy AND heat management.
It is a complex system but I think parts of it can be cut without losing too much. In this game projectile weapons required more slots and could run out of ammunition. In contrast to that energy weapons needed less slots, caused more heatup and needed energy to reload. Also a bigger engine produces more energy.

You could do something similar with slots, energy management and good auxiliary systems. For example armor is nice, but maybe you should add a shield that also costs more energy - maybe not. Add some booster that gives speed-boosts for energy, scanner systems, targetting etc. Also restrict space in the most central part so that you can not fit everything into one area of the ship AND protect this area best at the same time.
