Fate 3.0, actually.  I was out and about and ended up at Imagine Games and Hobbies, where I purchased the Spirit of the Century sourcebook.  Very interesting.  More complicated than DRYH but somewhat reminiscent in feel.  Evil Hat seems to be into cooperative storytelling, which I am also very into.  Maybe I'll find a opportunity to run a one-off of this - they advertise it as a "pickup" game.
