4. Mario 64 - Parkour 64
http://youtu.be/DTzs9bcNgMQ Did you know that it was actually possible, through the exploitation of a few glitches of course, to beat the entirety of Mario 64 in around ten minutes, without even ever collecting a single star?
Mitijitsu of YouTube does, and above he happily shows you how. Although how to actually recreate what you see in the clip is anyone's guess but I assume it's entirely possible with
a lot of practice and a great abundance of free time.
