Go ahead and join the 10001 game. The other started already. The 10001 game has 4 people in it currently, and I figured I'd start it in 10 or so hours, with a minimum of 6 people.
Don't know what the deal is, but something odd is going on. I played turn 1 (I'm Abyssia), and when I went to play turn 2, I got an error that my 2h file was from another saved game, and my turn was stale
