Nintendo will bring its make-your-own-Mario-level software to the portable 3DS system this year, but you won't be able to share your creations online. Bummer.

Super Mario Maker For Nintendo 3DS, to be released December 2, seems to be more focused on playing. It will include 100 levels designed by Nintendo, each with various extra challenges, such as completing the level while killing all of the enemies, or collecting every coin. Meanwhile, you'll be able to load up an automatically-generated, always-changing list of different levels that were created by players on the Wii U version of the game that Nintendo released last year.

What you won't be able to do, that you can on the Wii U, is enter in a download code to play a specific level. And most importantly, once you create a level on the 3DS, you can't upload it and share it around. What you can do, Nintendo says, is share that level with other players via local wireless.
