13. Super Mario World (SNES)

The first Mario on the SNES console, and it did not disappoint.  it was very much like Super Mario Bros. 3 in terms of mechanics and various worlds, but added elements, one infamous character (Yoshi), and tweaked a bit of what you could do with Mario in some regards.  Essentially, it focused a lot on developing what Mario could do with Yoshi.  I would say this is just a step above Mario 3, but of course the graphics improving helped out a bit as well.
