Oh man, the NES. Good times. All this talk about it is making me want to bust out my NES and blaze up to some of my favs:

-Arch Rivals
-Battletoads
-Duck Hunt
-Super Mario Bros. 3 (or just the entire series)
-Dr. Mario
-Bubble Bobble
-Paperboy
-Mega Man series
-Shadowgate
-Contra

And I always wanted to play:
-Metal Gear
-Final Fantasy
