I already reviewed 3D World on the Wii U so I am just going to say the game is an absolute blast.
As for Bowsers Fury, this extra is fun af. It feels completely different from anything in 3D World despite being built from 3D World. The gimmick of Bowser awakening every so often and attacking the player is really cool, and having Kaiju battles with Bowser is fun as well. The level design is very solid and collecting cat shines is satisfying. This is definitely the best Wii U port on the Switch and is worth it even if you played the game on Wii U.
