A new world record for the wii u game super mario 3d world any% speedrun has been done by a Japanese player! 1 hour and 48 minutes just about! The full video can be found here! (NO GLITCHES OR CHEATS!)
(The full game is about 15 hours on a non stop normal run)
I actually tried to beat this record but could only amass 2:50:00 so if you do try then best of luck!
