What other games do you want to edit in Mario Maker?

[Never]

I hope this means they're going to fully utilise The Mario series with the option of building levels for SMB2 and 3.

I'd dream of getting the whole hog though. A level builder where you could build levels for any of your fav NES era sidescrolling games. All the major Nintendo NES platformers (I needn't list them). All the third party ones (Megaman, castlevainia ect). And a ton of obscure Nes classics (I probably do need to list them but I'd be up all night). Then throw in a handful of Mastersystem classics.

...Then allow you to build hybrid games and watch my head explode.
