Voted for Change the game so people can drop in and out as they please.
I haven't played it a lot, but thought it was fun. My biggest problem was that I had to check on it every day and that the earlier someone commented to bigger his advantage was.
I could think of some things which might improve the game:
- In my opinion there should be a clear order in which the players act. (No clue how to solve if someone isn't playing).
- You should be able to not play for a view days
- automate the game, so that you can see right away if you are doing a foul move.
Good luck! I would love to play it again.
