One it's been worked on the longest(I think) out of the ones this year. Also it's Bioshock. One of the more refreshing FPS games out their. Also it focuses on the campaign, and looks to have some interesting characters like Elizabeth.
Also Bioshock Infinite reversible cover art is AWESOME.
Average mind set of SOME GFaq Users If it's the same it's boring. If it's different condemn it to death.
