What do you like to do when you're not dead yet?

I'm saying, if you've made good friend and allies in one game, it's more likely you'll befriend them in another also. Therefor there will be better diplomacy. You can say whatever you like, but that's how it works, at least from my experience.
I'm not saying you'll be in league with them from the start, but less likely to attack each others. But if it does happen, hey what the hell, it's only a game.
I sometimes make deals with some players, the first one to go down gives everything he has to the other.

EDIT: WingedDog, if someone screwed me over several times, you bet your ars I'll keep an eye on him. That doesn't mean I'll attack him in all other games of course. If that were the cast I'd never win a game. It means just what it says, I'll keep a watch on him, and prepare myself.
