I signed up to a 4 man double game today as the first player in team 2. Not long after me a new player joins and has the first turn (sequential). In this turn he takes 2 of my territories and 1 from the other team. Fron the initial 33 armies he started with, he now has 23 left, while my 30 are down to 26. Team 1 won't have much trouble winning when someone does this in the first turn.
So I sent my partner a PM explaining the idea of double games. But for this game (and another double game with someone else he already ruined) it will be too late.
So how do people handle those things?
And what is the best way to protect myself from ending up with those players?
