Remember the days of the Nintendo 64 and the original Xbox where you would sit down with your buddies on the same couch and play some games? You know, way back when you could smack the person who was using cheap maneuvers, like using Oddjob in Goldeneye 007.

That said, the Xbox 360 has a few gems hidden in its library that are an absolute blast to sit down on the couch with your buddies or significant other and play through.
