TT Games, which includes the studio Traveller's Tales, is best known for its LEGO games, which all started in 2006 with LEGO Star Wars and went on to sell countless millions worldwide. The series has undoubtedly influenced plenty of modern games too, but it seems TT Games design director Jon Burton believes the newly-unveiled Disney Universe goes too far.
On his Twitter account, Burton said:
Disney rip off our LEGO games and Little Big Planet to create: http://tinyurl.com/3z492d5. Best of luck to them.
And later, more specifically:
Disney Universe: drop-in/out co-op gameplay, play thru several films, adaptive difficulty & abilities based on what character u r =LEGO 2006
