It is no fun to win every single game you play... You have to lose some.
That being said... I have never betrayed an ally (not regarding trade "alliance" as an ally...), and I try not to ally with people I suspect might do so to me. It isn't much fun backstabbing people just so I can play a few dozen more turns... There are always more PBW games to join. [img]/threads/images/Graemlins/Lightning.gif[/img]
