I've played FAE in the Dresdenverse. It was street-level stuff, I played a frat boy who ran afoul of some low grade red court baddies.
There were squirt-guns full of holy water, garlic, crosses, a street-mage doing subtle stuff and a lot of low level politics in the spooky set messed up by saliva-addicted college students and a few other folks who got involved.
It was pretty fun as a one-shot, and less complex than trying to get a handle on a DFRPG character for a 4 hour gaming slot at a mini-con.
