It's one thing to master a game and find the secrets hidden in every nook and cranny to 100% complete it. It's another to defy the odds and manage to set records people didn't think were possible. That's what speedrunners are, though. They're essentially technological wizards, impressing us with their prowess and skill. And damned if what they do isn't fascinating.
These ten games are some of the best ones for speedruns. People have accomplished great things, and we're going to salute and acknowledge that by watching them do things like get Tetris' highest score in under four minutes or catch 'em all in Pokemon in about two hours.
