i think that dirge, jamiet et al fail to understand our point. i can't speak for everyone, but i'll speak for me:
ppsc is not diplomacy.
it is not a variant of diplomacy like modern, public press or gunboat, it is not diplomacy. if you think like this, it should (hopefully) be obvious why you would rather have unbalanced variants than ppsc on a site that labels itself "the best site for online diplomacy". you may not think like that, but you can't deny that if you would, this would likely be your opinion.
so why do i think ppsc is not diplomacy?
we can all agree that the goal of diplomacy is to win. that's what we're all here for - a solo victory. some may be here for different reasons, but i am talking about those who play the game to win, which should be the majority.
as jim pointed out, this leads to the paradox that you need to work with the very people who you will later have to betray in order to win. this is the core of the game – to win, you have to have everyone against you, at least at some point. this is done through negotiation, and things like develop tensions between your enemies etc.
it is not really important whether or not you do this on the standard map designed by calhamer. even if you change the map, the core of the game remains unchanged.
it gets a bit trickier with public press and gunboat games, but the basic idea is that you still communicate, only in public or without words. but this is a different discussion.
now to the points system – as people have pointed out, there is no ideal scoring system, because there is no description in the rulebook about playing more than one game. the problem with points is that they create a different incentive than described in the rulebook. so what you’re trying to do is keep that incentive as close to the rulebook as possible.
with ppsc, the opposite is the case – this system has incentives that contradict the core, the goal of the game, by rewarding players who help other players win. as i said, to win, you have to have everyone against you at some point. thus, helping another player achieve a solo victory (we’re talking about a conscious decision here, not being convinced that the leader is not a threat etc.) goes against the core of the game.
the ideal option (and as I understand it, the long-term goal for this site) is to not use points at all. and when this happens, I don’t want to play with people who think that surviving while someone else wins is good – if you survive, you’ve lost, because there is only one winner in the game of diplomacy. everything else is fine as well, of course – but it is not diplomacy.
