What is your most favorite Nintendo video game?  

I too enjoy Mario Kart as one of my favorite video games. I enjoy it most on Nintendo 64 and Gamecube. I think a game that tops even that is Super Smash Bros. Melee which has a very strong following with a plethora of tournaments that take place even today. Basically Mario games are the best because the reach out to all ages. Mario Party can be fun initially but it gets old. I'm going to have to give it hands down and then Mario Kart in close second.

favorite nintendo games?? well there's a lot actually but the only game that I always play on nintendo is. . . . .POKEMON! love the anime and the game..^_^

Yeah Mario Kart is really, cool, and it's a pretty good game, I mean the game can really be fun with lots of people playing multi player. But I must say I do enjoy Zelda the most on Nintendo. Followed by Mario. I like the original Zelda for the NES, and I play it on the Wii. I beat the first Zelda, then Link to the Past on SNES, and I just beat Ocarina of time for the N64. I play all these on the Wii, and it's a lot of fun. Have a great day.

I would definitely say Super Mario Bros is my most favourite Nintendo Video Game.
Both on the old NES, Gameboy, Wii and DS.

Aww, do I have to pick a favorite? It's so hard.

Well, assuming we're only talking about first party games (those made by Nintendo themselves), I have to say The Legend of a Zelda: A Link to the Past. That is one of the most awesome games ever created, and, in my opinion, the best Zelda game as well.

If we add third party games to the mix, then it'd have to be one of the games from the Dragon Quest series. I'll just say Dragon Quest IX because that's the one I'm currently playing.
