This late release is not the definitive version of Bioshock. The game is essentially identical to last year's release, which for all intents and purposes is a good thing. However, when this includes the game's detractions as well. While most of the detractions are negligible, it is disappointing that the game is being slugged at full retail and then asks you to pay more for the challenge rooms, especially since it has been available for over a year now. Still, this happens to be one of those games that didn't need to be tampered with much. For those who only own a PS3, this is a unique and immensely well-made experience that will stick with you for some time. That is, unless you have already played it.
