Now have I tried Little Big Planet (Demo), and I think it was okay. It wasn't like "ooh let play more" or "ooh I got to buy this", and it wasn't like "oh, this sucks". I think it was a okay game, a game I could play if I was bored or something, not more than that. It was a bit comfusing on the camera etc, but it went well in the end, haha.
Well, well, I'll rate it: 6/10!
