How about adding a new option for Standard play, that in those situations where you make an alliance you could "double up" with someone else and suddenly develop a Standard game into a part doubles game.
Why?
- Because sometimes you need to make an alliance to end a stalemate game, but "there is only one winner".
- Sometimes you make an alliance in a game but have to eventually kill your ally (which can feel quite rotten)
- Singles games could get interesting development where you start finding a partner mid game.
I just think this could add a very interesting (and in some cases vital) aspect to the game.
In my opinion there should be an option to double up with someone even if every one else play single. The ones playing single win all the points for themselves if they win, but if you double up with someone you have to share the points.
