I feel that this is a perfectly fine single player LittleBigPlanet game. Although it won't be my go to game in the series simply because not only are the other games better, but also because of the wonky physics and hit detection. You tend to die due to being considered too close to a hazard or just… because.

Plus, when the game first came out, it obviously had the simplest Create Mode compared to other games in the series, and thus the creativity didn't quite measure up to what you could do everywhere else.

I'd say only check it out if you were curious about the LBP series, and can get a PSP to play it.
