Hm..
My first memory is Donkey Kong Country. I remember thinking it looked amazing but man, I was terrible at it. I am the youngest of three, so I was pretty young when the Super Nintendo came out. I remember having those old televisions that had sticky buttons. I remember playing it all of the time but never making progress, lol.
Mario Kart 64, Mario Party, Ocarina of Time, Goldeneye, and Smash Bros. were some of the most fun I had in gaming. My brothers and friends killed our hands with those games. I was never particularly good at any of them, but man, I loved them.
Recently, I thought Super Mario Galaxy was the best Nintendo game in a while. I remember my mom picked me up from school and we drove to Toys R Us to get it. I think there was some type of commemorative coin that came with it. I loved that game so much. Also, Smash Bros. Brawl. Man, I will never forget that launch. It was a COLD, windy day here. I think I went to Gamestop at like 7:00 PM and waited five hours with everyone, just talking about the series and who we planned on using. I got home, played it all night and all day the next day. It was my longest session with a game. I loved it. Can't wait for Smash Bros. on Wii U.
