It's a pretty game with interesting gimmicks, which is why it gets a 9, but otherwise a let down. It does not sustain interest as did the first two Bioshocks. Definitely a rent, but dubious as a purchase.
The environment is beautiful and the gameplay is above average. Gameplay is a tad more difficult than the previous games. What I didn't enjoy was the inability to carry more than two weapons at a time. The previous Bioshock games gave you a variety of weapons that you could keep with you throughout the game. The vigors are okay. But the storyline was a bit confusing. It seemed like they just put whatever together for the storyline. I'm not done with the game, so I'm hoping everthing will come together in the end,
