Strip away the cuteness of Little Big Planet and you're left with some decent platforming and minigames, along with a complicated set of creation tools that will probably make you wish you spent your time doing something else. There's a reason the fan base for this series is relatively small, even after multiple versions have come out, the game just isn't that good.
you just hop around slowly popping bubbles and moving cushions. Its not fun or exciting. I guess the appeal of the game is the customizeability of the levels and Sackboy, but designing levels for... slowly popping bubbles is boring too.
