When you set up a game, you are offered a variant/map/rules choice. The default is "Standard," which by my reading means that games follow the Avalon Hill Diplomacy Rules (when set to default) or the specific variant rules (when set to a specific variant). This means there is winner. When you are offered a choice between Winner Takes All and Points Per Supply Center, the only info you are given is the following:
"Points-per-supply-center vs Winner-takes-all
For more experienced players who have over 100
there is a "Winner-takes-all" mode, which can be chosen instead of the default "Points-per-supply-center" mode. In winner-takes-all games the winner gets all the points from the game, and the runners up get nothing. This mode is for expert players who think that winner-takes-all is more true to the board game; there's no honor in second place, and playing for second place makes the game worse!
But remember that you are less likely to get any points back in a winner-takes-all game; even if you play well you might get no points back, so try to bet less on winner-takes-all games than points-per-supply-center games!"
This only states that if you choose Points Per Supply Center, you will get vDip points for finishing the game when you don't win. It says nothing about alternate victory conditions, i.e., there is no winner in Points Per Supply Center. And in fact, a solo is awarded based on the same conditions of both the Avalon Hill Diplomacy Rules and the specific variants rules. So, how are members supposed to know that normal victory conditions, as stated in the Avalon Hill Diplomacy Diplomacy Rules, do not apply in Points Per Supply Center? I've been here for a couple of years and I've never seen that quote of Oli's before. I have heard others say something similar, but I've also heard yet others who say you should still play to win in Points Per Supply Center. This should be clearly defined in both the game setup and in the FAQ - particularly since it is the default setting for games -- which goes against the Avalon Hill Diplomacy Rules that I think most players would expect we are following when a default game is set up.
