We have no earthly way of knowing who YouTube user TheFinalBurst is, but we're pretty sure the mystery creator's series of videos from the LittleBigPlanet 2 beta could serve as more effective marketing for the game than any ad campaign Sony could put together. Over the past week, TheFinalBurst's managed to create some mind-bogglingly intricate games using LBP 2's tool set -- games like Pac-Man, Micro Machines, an air hockey mini-game and even a first-person shooter, which we're still trying to wrap our heads around.

Check out a few of our favorite selections after the jump, or visit TheFinalBurst's YouTube page to check out all of this homebrew designer's brilliant creations. Those beta invites can't arrive soon enough.
