30th - Super Mario World
SMW is one of the best plattformers I have played. It was very enjoyable and the world map system was a very neat idea of Nintendo. This game also introduced Yoshi, one of my favorite characters in video games.
The gameplay was top notch and the soundtrack was catchy. I see little faults in this game, except the dificulty. The game was too easy in my opinion, however the game saw high replayability from me and I have probably clocked in more time on this game than Yoshi Island (the longer game). I can say that this is the best 2D Mario game, but not the best Mario game. You will be seeing a few 3D Mario games, on my list.
