In college, my boyfriend found his old Apple ][ and set it up in his dorm. We would play Oregon Trail for hours. His roomate was always one of my kids - poor Dave. He'd get dysentary, snake bites, broken arms...he eventually died, hehe.
When Dave bought his SNES to the room, I made a bet that I could clear all 96 states of Super Mario World in less than a week (meaning finding all the hidden worlds, all the special stages, etc). I won that bet easily
