Super Mario 3D World is basically Super Mario 3D Land but better. Same mechanics and general game level design in a much more clean implementation. As the previous game, there is a ton of post-game content, and I loved it. The Mario Galaxy references and the final level is the cherry on top for me.
Bowser's Fury is... complicated. It feels like a very big Mario Odissey or Mario 64 level packed into a single game, and in general it's pretty cool, but I think it's kinda half-cooked. It's very easy to feel like some shrines are repetitive or boring and I don't think the whole "Bowser will attack you every now and then" fits well such as it is (although the battles with him are really fun). If the general concept was more developed and there was more diversity in the shrines, I see this being like the ultimate "3D" game, but right now is just a funny little game mode.
