I'm not going to have "units". Basicly, the character will aquire new members, up to 5 on their team. I don't have to worry about balancing it but I do need to make sure that mages and fighters, the two extremes, are balanced. I've also already figured out all the stats. I dont need to worry about the "asshole" effect because it will be H2H meaning that both players will be in the same room. You won't be able to shoot on a diagonal. The character in front will get hit if there are two players. Basicly when you click on a character it will show you what you can do, who you can attack and where you can move.
*UPDATE* - The game now has a menu and premisis for the items. I'm working on the character creation system and the character concept.
