Yeah i mean the user made stuff is great, since its made by other users you could say its "multiplayer stuff" i guess, somehow, but theres something that bugs me in co op action, and is that sometimes when someone jumps to the edge of your screen, no matter how big is your tv and what resolution its at, the game will zoom out so much you wont see shit. And when for instance 3 dudes are on the ground, one grabs on a giant wheel, the cam will zoom out and zoom in back and forth.. Really annoying..
That and for that kind of game, i just cant see the reason of the multiplayer.. Reminds me of sonic 2 with tails: completely pointless, just flying around stealing rings and thats it.. The only thing where you need 2 players or more on LBP is just for getting those useless decorations, one stays on a switch meanwhile the other jumps around like a fool getting the stuff. wtf? pointless.
But i had loads of fun on the single player mode, and some levels are hella challenging.. And above all: its a super original game, and with really funny looks, definitely a unique masterpiece.
