Its the best game ever.Of course i played a lot of games , and this game includes in the best ligue of games . I think that Bioshock 2 completly opens all details Failing of Rapture and makes you wonder about relations between Father and Doughter.All Endings depend on YOUR chooce and really well deserved .Gameplay of Bioshock have endured evolution and now we can see upgrade of weapons and we have a lot of Tonics and Plasmids improves.I like Rapture more than Columbia because of atmosphiere of Rapture:People,Technology,Falling....And of course people nowdays can build Rapture but Columbia now is "Space".
