Althought I really dig XBox, specially for Ninja Gaiden and Halo 2 (cant go wrong with a 16 player fragfest), I can state that the SNES was the best of its time, and still rocks. Probably because I was a kid at that time and played much more time than now, but it was unforgettable.
Every game on SNES seems like it was perfect. I wouldn't change a thing about the system or the games. The simplicity of them made them more fun than anything.
True, kept simple, fun and entertaining not all graphically enhanced games are as great as the ones SNES presented.
