These threads always make for entertaining stories: so what was the dumbest thing(s) you've ever done in a video game? Something that made you pause and then think "wow, I'm retarded!"
I don't think I'll ever be able to beat the story of when a friend and I were playing the NES Ninja Turtles game and spent like 30-40 minutes trying to pass this stupid hole in the ground on the second level of one area... and then one of us had the brilliant idea of just trying to walk across it.
In RPGs, I've also been given the direction to "go west to ______" and then wandered off due east and wondered why I couldn't find anything. This has happened a disturbingly high number of times, though I've never had a problem with such directions in real life.
Anyway, share some stories.
