It isn't possible To have these factions together (cube is completely on its own)
Reasons why I can't have them together.
-Cube uses bricks.
-Ballz uses Gold
-Both Resources Are the same (Gold Resources) ingame.
-I don't want to convert The cubes to gold or ballz to bricks
ok....i got this idea from a game (it would be wise to listen to me):
the two factions have unique resources (the cubes get "bricks," and the ballz get something else)
they can only use their unique resource, and the two resources would be equal in size and amount.
every expansion point would have the same amount of both resources at them
late game (like, "brick factory" late game), both factions receive a way of harvesting the others' resource (only at a much reduced rate). this resource can then be converted to their resource.
there, problem solved (although a few new units will need to be made, but you guys are good at that
)
