Running my players through Dante’s Inferno might be an interesting idea. It’s not even close to original, but I think my group would enjoy it – killing demons/devils is pretty black and white and I could even have them encounter a few redeemable souls on their way through.

Aparently Monkeygod Enterprises did a sourcebook for this. Their productes are supposed to be on RPGNow soon.
