I have to say that Nintendo is the best gaming system ever but that is just my opinion.
Overall I felt that Super Mario Bros. was a great edition to the Mario family. With new mushrooms that let you shrink to fit in tight places and your ability to become a colossus with the giant mushroom. I rely enjoy the slim design and controller configuration. It is easy to play and the controls are well read. My only recommendation would be to consider utilizing the touch screen and L R buttons more. The only time it seems as though they used is during the extra worlds and the mini games.
