Yeah I have a controller for sure, several actually from over the years, but at that point in time why not just sit on my couch and play the games on one of my consoles on my 55" TV?
Obviously the graphics look much better on the PC, and trust me I have hooked my gaming computer up to my TV here and there, but my wife just absolutely hates my gaming computer in our TV room as the tower I have is a beast of a Thermaltake.

One of these days I was going to build a smaller more living room appropriate computer, but honestly for now as I said the consoles do pretty much suffice, except for FPS's, which I basically put up with the pain to play them on my computer whenever I can, as I definitely prefer a KB&M for them.
