PC. My god, PC. I don't know what it is about a first-person game on a TV, but I feel like I have no peripheral vision. It doesn't matter if I'm playing on a widescreen TV and a 4:3 monitor, I feel like I can't see properly, I feel like my gun is obstructing my view, and I feel like there's shit going on to the sides that I'm just not seeing. The only exception is Halo; I feel like it works on the Xbox and doesn't on the PC. Otherwise, it doesn't even matter what system the game was designed for.
