Why the hell are people in this thread trying to argue against the concept of console gaming? Go to the f*cking PC forum.
A console isn't diminished from adding more control methods. It's still a console.
Arguing that a mouse makes it a PC is the stupidest suggestion I've seen in a long time. PCs can use controllers, too, so the control input is not what differentiates a PC.
They can't play Metal Gear Solid 4, though, so stfu.
