I've played about 5-10 hours only but I really enjoyed it.
Combat is the typical terrible stuff you get from 2000 games (like Deus Ex), but the atmosphere is really great and the controls/graphics have aged pretty well. It really is pretty much Bioshock in space but with a more complicated inventory and stats/skills system. It's a good experience so you can appreciate the evolution in the games.
