Recommendations:
1. Each player plays his 10 turns and posts a BRIEF summary of changes he made and events that happened. It is entirely possible you could say "nothing happened and I didn't change anything"...early in the game. That's probably not true in the ADs.
2. Each player should complete his 10 turns and post his new save in the following day. So if we started on Saturday with mirc, then Trada plays on Sunday and posts on Monday, and Alex gets the game Monday and posts Tuesday. Due to timezone differences we should allow up to 48 hours before complaining about no post.
Concern: A game is 480 turns long, I think. Even at one rotation a day, that game will take a month and a half. If we increase each player's allotment to 20 turns, it means the game will last about 3 weeks. I recommend 20 turns per player until the late years. 20 turns in 4000BC means little while 20 turns in 1750AD means a lot.
