Well, it is! You should be able to pick it up in the Playstation store through your gaming console or you can download it online, either way.

Here is some footage of the actual game-play of Little Big Planet on the PSP Go that I discovered on YouTube of course -

You CAN still play on user created maps, which is a plus.

But I’m not sure if multiplayer is available on the PSP Go as of yet. When I find out I’ll keep you guys updated!

Or, if you know whether or not it is, just drop a comment and let everyone know!
