Depending on how old you are, when you think of couch co-op, you may think of things like splitscreen shooters from the fifth console generation onwards. However, that generation most certainly did not invent couch co-op, it just made it flashier. Gamers have been working together on games as far back as the third generation, thanks in large part to home ports of arcade games. Even if it only had two controller ports, the Super Nintendo in particular was a top-shelf co-op console.
