Just wondering if anything is under the surface of just creating levels for someone not into that? For instance are their new premade levels made or anything else outside of making your own levels?
The original came with some nintendo made levels, the 3ds version expanded on that and there are lots of "singleplayer" modes to play levels made by random people based on difficulty which rewards you with stuff.
And don't forget the official made levels that also gave you outfits like the pokemon, hello kitty or baby metal ones
The 10/100 Mario Challenges give you costumes.
