Inspired by another post, I ask: have you ever tried to do a speed run in any game? If so, which game(s) and how well did you do? For those not familiar with the term, a speed run is an attempt to complete a game as quickly as possible.
I've never purposely tried to do a speed run, but I have managed to completely a few games very quickly. I was able to finish NES Contra in just half an hour (and that's on two player, at that). I've done some of the Mario games, mainly Mario 3, easily thanks to warp zones.
