Personally I prefer high fantasy and soft sci-fi, but that's mostly because that gives a lot more room to work with (and lets you be a bit wacky if need be), but I'm willing to work with other genres if it comes down to it.  Although urban fantasy has always been a weakness of mine (I grew up with Buffy the Vampire Slayer, what can I say?), but we'll see what everyone else thinks I guess.
