Remember those days as a child when you were hanging out in your buddies basement on some old rickety couch, on the crappiest tv in the world and got your co-op on? I want to remember those days. The days with Gunstar Heroes, Battle-toads, and Bomber Man. A few years later it was *jet-force* gemini and gauntlet; Baldurs gate and halo. Marvel ultimate alliance and army of two. What game gave you the most hours of fun?
edit: I spent countless hours on Guantlet 64 with my two Neighbors.
