Nobilis Diceless Roleplaying
There's another diceless roleplaying game in town. It's called Nobilis and it sounds cool. Here's a description I found:

Nobilis is a diceless role playing game set in the modern times. Players role play incarnations of reality, called Nobles or Powers. Examples of this sort of character and genre include the Sandman series by Neil Gaimen, "Creatures of Light and Darkness" by Roger Zelazny, and the anime film "Princess Mononoke". The characters are quite powerful, although they serve still more powerful beings, called Imperators.

I'll have to look for more stuff on this game later.
