I've always avoided sci-fi games because of the hideous colorless depressing landscape, not to mention that I love fantasy & hate any sci-fi that isn't anime.
But after watching the demo & being wowed by the landscape, I think I'll try it.
It looks like it's more brite, colorful, & smooth-in-movement than Bioshock. Because bioshock looks like a consol port & has unrealistic movement speeds, that annoyed me quite a bit.
As an artist, the design is actually more important to me than anything else, 2ed by game content, then story, then playability (after a week of self-training, even the worst game controls can be learned, then fun is had!) & that's why I'll never prefur Diablo over Dungeon Siege.
