#16 - Super Mario World
The SNES is awesome and it started with the very first game available for it: Super Mario World. Improving on the already stellar Super Mario Bros. 3, this game introduced a lot of new concepts that are now staples of the series like Ghosts houses, Yoshi, replayable stages and secret exits.
Although you can reach Bowser pretty quickly thanks to the Star Road, the fun of the game is in completing all of the game's levels (even the ridiculously hard ones like Tubular!).
Signature goes here!
