I think 12 hour quickhost will make for problems, especially if you want a full game. It's nice for getting the game off to a quicker start, but eventually people are going to be away from their computers for more than 12 hours - weekends, long work days, etc.
And the 12 QH means that you can't count on buying yourself some time by being the first person to take their turn. Even if you take your turn while there's 11 hours 55 minutes to go, thus figuring you have almost 24 hours before the next turn, murphy's law says that everyone will then take their turn in the first hour, and in 13 hours (rather than 24) you get a stale turn.
That said, I'll probably be in, just to watch the R'lyeh / Atlantis hatefest that Orania forces in 17 player games.
Just gotta deicide if I want Vanheim, Man, Pangaea, Machaka, Arco, or if masochistic, T'ien C'hi.
