Yeah, the world record time for mario three doesn't really qualify as "rushing through" the game (err... especialy since it was accomplished using frame by frame... nevermind).
For example, I played Metroid Zero mission in like 45-50 minutes. That's kind of good, but nothing compared to the 30-ish times(that were done on hard mode, no less). Simply because I played through it at a furiuos pace did not mean I rushed through it, I knew exactly what to do from the get go(get mb, set missles and charge, go through the helish bee chamber, get mbb, go to Norfair, go to crateria, get ui1 and pg, go to Norfair, get ib, go to Ridley via the secret chamber in the northeast of norfair, get the non-boss battle sms, get UI3 and kill ridley, get screw attack(because I am not good enough to go without it), go to Brinstar, go to Kraid, get UI2, kill kraid and get Sb, go to Brinstar, go to Tourian, kill metroids and Mother brain, go to chozodia via samus's ship, sneak past space pirates and defeat the phantom, obtain any sms obtainable on the way to mech ridley, defeat mech ridley, and rush rush rush!
