Unholy Warlord
Update will be delayed a bit. The writeup is taking longer than I thought. 

A new DI rule involving the changing of the player at every round might be cool. This would achieve 2 things:
1. The game would not be dependant on one single human being, who might have RL issues, etc.
2. More people could participate in the game.
I do not think changing the player would be a good idea. The idea of this is to keep the human player the same, and watch him react to the various gods. Changing the player would disrupt the narrative, as well as undo a lot of the tempting that the gods are trying to do to get the player on their side. I don't think having multiple players is worth it, and would rather wait an extra week and get a nice story.
In regards to point number 2, over the half the gods that signed up are not posting. This game is very big, with 21 people involved (assuming MC as Arawn is not a joke). I don't know that involving more would help much.
edit: Having multiple human players at once could be interesting, though...
