Funny what a mod blacklist will do.
Considering I haven't played in a long time and Dan only flipped out at the end of last game from what I've seen, that would leave Rawr, which I doubt had that much, if any influence on the speed of sign-ups, so... yeah, most likely just the fact that it's you hosting.
ActionDan: If you count a draw as 1/2 win and if you simplify the decision to 100% chance of draw if no NK and 50% of win if NK, that seems pretty much identical to me, at least as far as a single game goes.
And as for what Zak based his choice on - if town is fucked either way, the only difference it would make is for some hypothetical future game with a similar situation that allows for a draw. Don't think that really should have factored into his decision.
