Should be interesting, I have no interest in creating Mario levels but I will sure have fun playing everybodys creations.

Nice! Didn't know Nintendo was letting other developers make the Mario Maker levels that are tied in the game(or is this something else?)!

And the thought never occurred to me that other developers with Wii U could be sharing levels online as well! I wonder if Nintendo will try to highlight these levels online. Would be cool to play a level made by a developer outside of Nintendo!

Awesome. I love the levels in Rayman Origins/Legends so this should be good.

Never played Rayman so this should be interesting

Not particularly interesting. Notch designed one of the levels in VVVVVV. It just played like any other level. You take people into a new area of expertise, you don't tend to get anything special.
Granted Rayman and Mario have some overlap. But I think I'd be fine just with the Nintendo levels!

Ancel's level will be among the best.

This is awesome and a great move by both parties. Nintendo should assemble a group of all-star level makers, like a Sonic vet or a level inspired by Mega Man.

Cool
