OK, so here's the deal. The 360 version, to your disbelief, plays it at a much higher visual quality than PC. Here's why, on 360, it is put out at a much higher resolution that the current graphics cards offer, at silky smooth frame rates, and with 4xaa and 4xaf, other than that, the same textures, effects and models are used. You may have noticed serious jaggies at kiosks, that's because the screens they use are crap, 420p, and they are not using the high def plugs, only the s-video plugs, so it doen't work right, and gives off crazy jaggies. Other than that, i have to say teh controller of the 360 is amazing, but, on this game, it's really hard to aim, so i prefer the pc version for this factor, because it's cheaper to just use my existin pc and crt monitor than to buy a xbox360 and an hdtv, also, with my mouse and keyboard, i can get head shots all day.
