Ha, can't you just tell whichever way we go everyone will complain

In answer to the original question, I think the bugs which cause many multi-human games to get stuck mean most players are put of playing when they know they will likely play for an hour and then the game will be lost. So I think people played at first to see what the game was like, but it's too unreliable to play for real.
That's my $0.02 anyway - we still would love your feedback. Are you not playing PM2 because of instability, because you hate it, or just because nobody else is?
