TAS: Genesis Sonic 3 & Knuckles in 29:51.2 by Nitsuja & Upthorn & marzojr
Sonic 3 & Knuckles is one of the few games that becomes very entertaining whenever a new run gets submitted.
This run takes everything you know about Sonic 3 and Knuckles and turns it upside-down. It extensively uses the "scroll objects offscreen to pass through them" trick to zip and warp to places that shouldn't be reached, break bosses, and effectively skip entire stages.
The run aims for the fastest In-game time rather than real time.
Example: clearing the stage with 31(+) in-game time seconds is much faster in real time than clearing the stage in 25-30 in-game time seconds. It looks silly for players aiming towards the fastest possible real time run.
Grand total In-game time: 19:44::57

World Of Goo Speed Run by ridd3r (0:53:41)
World of Goo is one of the highest rated games on both Wiiware and Steam, it recently came out on Apple's iPad. This run never uses the 'skip a level' option and it shows a good amount of exploits in the game/physics engine.
