I'm pretty eclectic, partly due to taking a lot of commission painting and conversion work. Nothing like it for broadening your horizons. Probably biased toward scifi in general, but there are few genres or periods I won't try, given the opportunity. Quite liking Mantic's Deadzone and Alien Dungeon's All Quiet On the Martian Front, although I'll concede they have more than their share of warts.
