Super Mario Maker was such a beautiful concept that created some amazing levels and gameplay concepts. The sharing of levels and seeing how the community used the tools was really the glue that kept it all together.
Well, the game is coming to 3DS this year on December 2nd, which is pretty exciting. It will mean you can make levels and try out new ideas on the move. However, there is a big caveat. You won't be able to share or download other levels from the internet, instead only being able to share locally.
This is a pretty huge asterix for this game as the sharing and playing abillity was really what made it special. Still, it is cool to have a version of the game on the handheld at least.
