Ah, the good ol' NES. I'm not even a huge Nintendo fan, and yet I think the NES is a brilliant system. I mean, it brought us timeless classics like Super Mario Bros. 3, which is still a great game, and it innovated the gaming industry.
This was back before Nintendo devolved into remaking the same boring, repetitive "New" Super Mario Bros. every year (Seriously, I don't know why Nintendo fans defend this move but bash CoD for doing the exact same thing). This was back when a new Mario game meant a new adventure.
But seriously, the NES was and still is phenomenal. It brought us so many great games that there are too many to count.
Now the LJN games, on the other hand...
