I enjoyed a negative review of BioShock partly because everything else I've read so far was full of praise, and partly because, immersive as it is, really is overrated. For one, I couldn't believe that I was restricted to basically one environment, and I got so lost around the repetitive-looking environment just as I was in Halo: Combat Evolved (a superior game, even considering it was released over 5 years earlier).
What I like about the game:
- an amazing array of genetic weapons
- great art direction
- the fearsome Big Daddies
- an appealing gloomy storyline of genetic engineering gone awry
The whole thing did alert me what a tremendously useful tool 3D games could be as exploration tools to unfamiliar worlds. Note that I've lived through such an experience with the vastly underrated Conflict: Desert Storm.
