13: Bioshock Infinite
No game is perfect, but Bioshock Infinite comes exceedingly close.
This game has it all: a richly imaginative plot, exquisite graphics, nearly flawless gameplay mechanics, and a fabulous soundtrack. And unlike some other ambitiously designed games, this one won’t bring your average PC to its knees. It will take full advantage of any state-of-the-art gaming rig; but dial down the resolution just a wee bit, and you’ll get a great experience even with integrated graphics.
If you buy only one PC game this year, make it Bioshock Infinite.
