Possibly the greatest Mario, thus far.

Alright, terrible secret, I never really played a whole lot of mario 64. I enjoyed it, but never beat it and never got more then 28 stars. I never owned it, and thus never had the time. That being said, I find the pinacle of 2-d platforming was reached in Mario World, i never got all the paths, but i was only missing one, and i know where it is, i just suck too much to get it. But i aced the star road so there. If you actually need to read this review, just give up on gaming. The mario games through 64 dont need reviews anymore. This game has it all, fireflowers, the cape, yoshi, different color yoshis, mode 7, kick ass mario esque music. Ghost houses, Castles, water levels, forced movement levels (no idea what they are called otherwise) points (something not enough games have anymore0 the works. Platforming at its 2d finest.
