True, it reminds me of LBP and even a bit of ModNation Racers. And sure, they might have borrowed the idea from there. But if we're gonna start analyzing games with stuff like "Where did they rip this from?", then 90% of the games out there are indeed a rip off of something else. Some are more obvious than others.
But if anything, it was inspired by LPB and they took the idea one step further. It seems the costumes give you different abilities here. And sorry but I don't see how this is a rip off of Lego Universe or whatever. Legos are all about building and destroying. I don't think you can do that with these Disney characters. So like someone said, if anything, the producers of LBP should be complaining, not this guy.
