This is a speedrun of Psychonauts where the speedrunner is playing in a room full of the game designers. It's not a world record or anything, but it's fun watching the devs react to him breaking the game. The best bit is at 27:00.
Last time I played, I got stuck at the Napoleon game board level. Oh, and the speedrunner, SMK, skips most of the last level, which is said to be the hardest level in the game.
