These kids today, don't know how easy they got it. We used to go to each others houses, wow actual interaction with humans. When we were there you'd have to pass the controller between each other because co op mode hadn't been invented and even if it had you only had one controller anyway. The best bit was your friends mum might make you dinner, if you were anything like me you dreaded your own mums cooking and a trip to a friends was a relief.
