It seems that more people like the idea of a limited number of units per tile than I imagined. After the initial feedback, I'm considering these changes: The limit only applies to your team. If the limit is 1 unit, it means 1 unit from each team can be on the tile. This should fix the problem where you can't attack a tile with too many units. Defensive units (workers, settlers, etc...) are exempted from the limit and not counted. Any other changes or additions along these lines you would like?
