I was playing the demo for Wizardry: Labyrinth of the Lost Souls. Stopped playing about 30 minutes ago, but there's still a decent amount for me to do (you're limited to the first floor of the dungeon, and there's a level cap of 5 -- but I'm a couple of hour of playtime in and I still have some areas to explore, and my highest level characters are level 2, plus there's an elite monster that needs to die).
I'm enjoying it, but I don't know that I'll be picking it up when I could just as easily play something similar on the DS (or download some abandonware) and keep the money for other games. Trophies are a fun incentive, but realistically, I don't know that I'll ever be willing/able to collect them all.
