15. Super Mario Maker (Wii U / 3DS)

Nintendo is notorious for keeping an iron grip on its properties, and if you play its 2015 platformer creation kit for a minute you might understand why: Left unchecked, most of us will create impossible troll rooms that double as torture chambers. Most people can’t make levels that capture, much less outdo, the simple brilliance of any single level from the first Super Mario Bros
But the beauty is in that same madness. Nintendo has, for the most part, moved on from 2D Mario games. Why not let players run wild with their own designs? Every so often, someone will put together a world that rivals if not outdoes Nintendo’s own creations. If nothing else, it was a hoot to watch people spend months trying to beat diabolical levels made by Satan himself, along with tinkerers pushing the game engine to its very limits. — Patricia Hernandez
