I finished Bioshock and I consider it a very good game. It had amazing atmosphere that really helped immersing into the setting. The shooting for some reason felt a bit off to me. I ended up relying more on weapons than plasmids, which probably wasn't the best strategy. Something about having trouble passing up all the ammo I'd find lying around. It had an intriguing story with plot twists, some more obvious than others. Highly recommended.
