On the way home, I was listening to a podcast and it brought up the question of God being on one's side. I think that would be an interesting campaign: the PCs are divine agents that have to enter into conflicts of all scales, from major wars to little league games, and tip the balance to whatever side that the Ineffible chose to back this time around. The PCs would be free to do whatever they wanted, but if they did not make the right side win (or the right side lose, i suppose) they might not get their jobs and have to go back to mortal existence or the Pit or whatever.
What system for that game?
