Are any of you still playing the re-released Super Mario 3D World? I've been playing it solidly for the last 6 weeks and I enjoy the replay value of finding all of the green stars. Worlds 1-6 are pretty steady going. The difficulty racks up a little in worlds 7 and 8, with the boss of the game being at the end of world 8, which I managed to defeat after a few attempts. Then there are 4 more worlds after the base game, and there are some tough nuts in there! Once you've completed some courses in the upper 4 worlds, then it goes make the previous 8 worlds a lot easier and so you can go back into those to grab some more green stars because you are now better at the game.
I haven't even touched Bowser's Fury yet!
Next up I think will be Mario Odyssey.
