Nods to old bugs that were in later games, and especially new 'features' were exactly what I was looking for. And now that I think about it, I remember that time-attack run of Quake I with rocketjumping being obscenely sick.
Vok's Ermac thing was also interesting. Screwy Midway. Even though it wasn't a real glitch, Ermac might deserve honorable mention for trying so damn hard.
But on the matter of Sheng Long, I'll pass. Probably because I really tried to fight Sheng Long when I was younger. Goddamnit.
