if you have a 360 or a good pc, buy this game. its so good, besides being a quality game the story, graphics and sound are truly a work of art. its quite creepy, too.
After playing the demo, I thought it was an ok game, it somehow got rated a 10 by Game Informer. I do not plan on buying it, it's not fast paced enough of a shooter. The graphics were pretty good, and the destroyable environment was good as well.
It definitely does NOT deserve a 10, in my opinion, no game deserves a 10. There has not been one perfect game ever. They can come close, but they have not yet hit perfection. And Bioshock should be an 8.5-9.5 at the very most.
Definately a good game, and I think it got 10 because it met expectation in all criterias that they judged it on. I still haven't finished it because of school and I bought Skate too. But definately a good game to play with all the lights out.
