I agree reputations are important.

I used to play board games with friends. There was one guy who always, always, betrayed people he agreed an alliance with, more often than not the first turn they'd agreed to ally. Everyone quickly knew never, ever, to make an agreement with him.

This is the real danger. There's a community here, and people play against the player. Experienced players will smash new players because it's easy territory, and players will not form NAPs with untrustworthy players. If you have have a bad reputation, you're stuffed in MP because diplomacy is so important.

Breaking NAPs can be done 'fairly', but I think the justification must be that there is a crisis situtation, such as the guy being about to get unbeatably powerful.
