Perhaps Sony and Media Molecule could have thought up a more clever title: LittleBigPlanet: Portable Sized Platforming ... or Pint-sized Super Playfield. Ignoring the fact that these are terrible title suggestions, we'd have to say LittleBigPlanet PSP works so well because it captures the simple essence of what this game is all about. This is without a doubt LittleBigPlanet on-the-go, nuts, bolts and stickers included.
The colorful world of Sackboy and friends translates very well on the PSP screen. Sure, the game is missing many of the lighting and particle effects that make the PS3 game look so good, but considering PSP's limitations, this is an incredibly good fascimile of the original. Even in its early state, the framerate holds up surprisingly well. Even more surprising: it appears the game's use of physics has been largely retained.
If the demonstration level at E3 is any indication, it appears PSP owners will be able to create levels of equal complexity as on the PS3. The level we played showcased the requisite spins, swings and grabbable sponges so integral to the LBP experience.
