You're supposed to play all 15 regardless, but two of us really weren't happy.
To be honest when we started game 12, me and one other player could only ever draw with the leader anyway, and that's if we won every game (12 - 15), so it was always pretty unlikely.
It's just the way he went about it left a nasty taste. It's a great game, but I can't see us pulling it out again for a while.
