More rare, is finding folks that can honestly admit to having beaten it. I picked up the "game and watch" recently, and I can't remember crap about how to make progress in that game. It is really really hard to remember where to go next.
Granted, the first game is bad at that, too. Especially on the second play through. Really difficult to have the same map be different in that way. Still have fun playing it, years later. :D
