Seriously though, they should remove large portions of Harry Potter world in LA to make room for Nintendo. Orlando Universal parks are already good enough. The LA park is a joke and Nintendo is more of a household name than that old 90's book.
That way, Universal Hollywood would actually be able to begin to compete with Disney. Harry Potter, minions and shrek simulators aren't going to get people in that park. Nothing compelling about beating a dead horse.
Pretty sure Harry Potter has a lot more appeal than Nintendo, it's one of the biggest movie franchises in history.
It would honestly make more sense to remove all the Simpsons stuff to make room for Nintendo than Harry Potter.
