Super Mario Bros 3 was also my favorite as a kid. I would play that for hours and hours. That and Blaster Master . Dun dun dun dun...dundundun. Bah Bum badadaaaa ... love that music
Zelda is my favorite Nintendo series, if i had to pick my favorite one, I would probably say A link to the Past for 2D and for 3D probably Twilight Princess (still not sure on the 3d one totaly yet).
