The Legend of Zelda, to the point where I regularly cosplay as Link at conventions. Last pride parade I went to was with an LGBT gamer group, where my wife and I marched together as Link and Zelda.
Metroid, Smash Bros., Legend of Zelda, Mario Party, Final Fantasy (yes, it was originally a Nintendo game. Nintendo screwed up and sold teh game to Sony and the rest is history)
Lol probably every Nintendo game! But if I had to pick, some of my top favorites are the Zelda, Pokemon, Metroid, and Kirby games. Also anything made by Nintendo for the N64.
That is cool! Do you have pics of it? I love twilight princess and the pokémon series and not sure of what else i like
