Noodlebug, I greatly sympathize, you describe the exact manner of play that I enjoy. However, players will always have their own separate objectives in a game, regardless of a points system, though they might not be as elegant in simplicity as a play-to-win, they are equally valid.
I would not go so far as to say that players who win games now do so by luck... But certainly there is less emphasis on long term planning and taking into account the balance of power. Because in my recent experiences it is usually the players who are very good at opening gameplay that rise to the top. This is because players who manage to expand well in the beginning usually find the way paved to victory, as the other players begin to negotiate solely with the winning player for survival and/or a profit on their points investment. As a result, short term success is, in my opinion, overemphasized in current play, and the beauty of playing the long game is slowly being lost.
cgwhite, I'm not sure how your medium-sized country example proves the benefit of draws... I'm sure I speak for all play-to-win promoters when I say that playing to win doesn't mean playing to maximize centres, as much as it means playing to ensure that nobody but you wins. With this in mind, if you played to win, you would NOT stab the remaining players, but attempt to fight the current leader. If you bring it to a stalemate, so be it, then it ends in a draw. But in the end, that should be the best outcome. Why would the leader settle for the draw when they can grab the victory?
figle, I don't think Noodlebug would actually have any problems with the current point system IF everyone played-to-win. However, economics and game theory say that this will not be the case. I like that the point system is graduated, it's just unfortunate that people aren't willing to fight for the victory if it's clear they won't win it in the next 5 years or so.
Just a reminder, "play to win" does NOT mean that if there is no chance for victory then one should give up. It means that there is ALWAYS a chance for victory. It only requires intense co-ordination in the face of adversity. And this is a wonderful thing.
