I am suggesting that you have to decide if you want to allow this game have allies or not. It would be part of a game type. Like, standered, asia, 3 player, chained, no allies. If you want allies you clck the yes allies button, if not click no allies. This can help avoid disputes about allying.

Alliances are a part of the game. If you control more than 1/n of the map (where n is the number of players still alive) and have more than 1/n of the armies, then you're going to be a big target for the others.
I was a major back when 1600 was major. Now that I'm back, I get to easily win a bunch of games to get my rank. Thank the 'tards here who suck at this game.
Personally I hate teaming so would like that as a game option. Not sure how it would be enforced but really hate teaming. Good players have sort of a silent teaming anyway, but posting messages on the game about truces etc is bull. Ruins the game.
