6. Sonic The Hedgehog In 15 Minutes (Glitch Run)
http://www.youtube.com/watch?v=KcnbOUkZ7ps Here's an extremely impressive speed run that takes advantage of a few glitches to gain precious time throughout Sonic the Hedgehog, though the player barely needs much assistance, as evidenced by the fact that he manages to beast his way through the entire Green Hill Zone in barely over 2 minutes. Given the ridiculously fast pace of the game, this feat is all the more impressive, requiring ridiculous levels of timing and muscle memory which most us couldn't even fathom. What's the best thing about it? The player declares
here that the run can be improved upon, though he will only bother if anyone actually challenges his mantle for the Sonic The Hedgehog world record, which we doubt will happen anytime soon.
