I'm going to trade all of my old games at Gamestop for some cash that way I can buy a new PSP game. Anyways one of the games I'm thinking about getting is Little Big Planet.

My question is: Are there any differences between the PS3 and PSP version besides the graphics? Like does the PSP version have more, less, or the same features?

Also another question I have is if Little Big Planet has any co-op on the PSP.

Thank you whoever answers!
