if you're interested in this kind of thing, The Mexican Runner beat every NES game (over 700 of them [1]) including such gems as Miracle Piano Teaching System, which took 91 hours to beat and required him to become quite proficient at actual piano playing [2]
He has already completed all games, but the videos are waaay behind (he's releasing one video/game a week).
