For me, this game is heavily carried by Bowser's Fury. Not a big fan of 3D World due to the fixed camera (Yes, it ruined my experience), but the levels are actually really fun. Which is why Bowser's fury is so great - It reuses the levels and powerups of 3D World in a proper 3D Mario World - and this is a big world which is fun to traverse. The final boss of Bowser's Fury is probably one of the best final bosses, its so gorgeous and exciting.
