Old now, but anyone else kind of feel World Bowser was what Super Mario 3D World should have been like in general? Felt like the one world with a consistent theme, some interesting story background and a somewhat grounded setting beyond 'stuff in space'. If the other worlds were that original, the game could have been a real classic.
