The basics are as follows:
-There are four basic types of units: worker (0 AT/1 DE), soldier (1 AT/1 DE), Leader (1 AT/2 DE), and philosopher (0 AT/2 DE).
-They can be upgraded, but the combat system doesn't rely on this i.e. it needs to be interesting independent of these upgrades.
-I need a surprise element and/or something to shake up combat so it doesn't get dull.
-I am only using cards and clips as components in the game so no dice.
-You must gain some sort of victory point for how well your attack was.
-I would like it so that attacking with one unit (surprise attack) is just as interesting/fulfilling as attacking with a group.
-There is no grid in the game so positioning is not required. Units could be lined up against one another, but there is no "distance" between units.
-The attacker must expend power in order to attack but the defender usually doesn't so the attacker should maybe have an advantage somewhere.
--It is a civilization game so this is one of a few major mechanics so it mustn't be to complex. Just enough so players find it interesting and strategic.
-The combat is more of a micro aspect of the game so the entire game does not revolve around combat.
... I will add an other info to create the context for but I think this is enough to spark some conversation. Let me know what you think!
