Some have spent days crafting their ideal custom worlds, including tributes to classic games and characters such as Final Fantasy, Pac-Man, Batman, Sonic The Hedgehog, God Of War, Super Mario Bros and Indiana Jones.

Even minor copyright violations such as references to characters from other games are being "moderated", and players are given no option to remove the offending content and republish their levels.
