Super Mario Bros. 3

The Good
Engaging gameplay, challenging levels, unlimited replay value, great graphics for it's time, a game that is as fun now as it was when it was released. I think the question is more of what is not good about this game. Simply legendary.

The Bad
The frog suit is cumbersome outside of water. Seriously that's it...

The Bottom Line
This is the ultimate game period. If you haven't played this game you've probably been living under a rock. In that case get out from that rock and play this game! It's the #1 game ever in my opinion and any game coming out would be hard pressed to beat it
