I loved the first Bioshock game. Infinite is better in every way.
I'm not one of those misty-eyed "games are art" douchebags (more accurately, I don't really care whether or not anybody thinks games are art, and I don't have much of an opinion on the matter), but that game is a masterpiece.
I wish I had gotten a PS3 just for that game. It feels too late to buy one now, barring a huge price drop, and the PS4 doesn't have backwards compatibility.
