Ok this will be different from various chessboards I am sure you have in the Map Foundry what I am suggesting is a whole new Mode of play under the Game type section(Standard, Terminator,etc)
It would be a variation of team play for the various boards but would only be a 2 player Game with each player having control of a predetermine set of team divisions. Based on board capacity 3 divisions on each team on smaller boards and the larger boards having 4 per team.
The object would be for a Generals team of divisions to win on the game. The 2 players like on any other team game would have to figure out how best to overcome the other team same as always but it puts all responsibilty on the general controling the various divisions on his team and using them to the best of his ability.
Card Play, while I would probably enjoy this best no cards I think all card play game types should still be present. Each division on a team should also be able to get its own cards without them being inter-playable as far as matching sets between divisions.
This could be player in sequential or freestyle like all other game types the resulting play would create a lot of forethought like chess each turn. Sequential of course in this case would be simpler then freestyle but each way playable and challenging.
Now downsides to be overcome if possible. Speed games would be almost impossible on freestyle. 5 minutes I do not think would be enough time to coordinate an assault with current control system.
Unless there was a type of multi control mode to be unlocked under this control menu. Where you have your team parts broken down kind of like territories in regular attack select and even then I believe it would be hard but possible.
I got this idea in part of course by playing chess and getting bored with what I feel is alack of forethoght involved in Regular CC games. I like how team games are more fun and challenging but still not the level of challenge I want on a game I need a little more thought on it like I do when I play chess.
Then I was reading through forum and looked at cheating and abuse with all the multi players. I thought how unfun that would be letting myself win by playing all sides in a battle. But why not be the general of 1 team calling all shots. That way there is no one to blame or leave a negative for if you do not play well other then yourself. Also it might somewhat help with the habitual multis getting a mode inspired in part by them lol
