Bioshock Infinite is great, it's the first time in a LONG time that I've felt a First Person Shooter was actually great. The gunplay is tight and fun, the powers known in this game as vigors (which are essentially plasmids) are neat, and the atmosphere and scenery are amazing to look at. Storywise, prepare yourself for a ton of religious overtones with a bit of white guilt sprinkled in. I'd say my only complaint so far is that the game throws too much ammo, healthkits and money at you to be challenging, but I'm only playing Normal for now so I expect this to be changed on higher difficulties.
So yeah, whoever you were, go buy it n' stuff.
