Mine would have to be Yoshi's Island. I just loved being able to play as Yoshi and having baby Mario and baby Luigi and it being Yoshi who had to take care of them and ensure they were safe. This game when it was released was a game I spent many hours on after getting it with my brothers.
Conker's Bad Fur Day. Why? Because I think it's one of the first games that had ever exposed me to the raunchy adult humorous side of things and one of the only games by Nintendo that was rated A.
I would have to say Pokemon Gold/SIlver games, or Ocarina of Time. Never really played too many Nintendo games, but of the few I played, these were great
It's probably Fire Emblem: Genealogy of the Holy War. There aren't many games I've enjoyed playing as much as this one. The story is great, the music is amazing, the characters are good, the chapters are epic and it has a very special SNES feeling to it.
Honorable mentions to Path of Radiance, Zelda: Majora's Mask and A Link to the Past, Pokémon Yellow and Chrono Trigger.
My favorite Nintendo game would have to be the original Zelda: Ocarina of Time for the N64. I played it through multiple times. I haven't had the chance to play the remake so I can't be a judge on that. I did hear it was a great improvement. It's been awhile since I've played a Nintendo game. I'm not sure if I have any more current favorites.
My favorite was Super Mario 3 for the first Nintendo console. I enjoyed playing it so much (and I believe I would still enjoy playing it now). I liked how each world was something completely different, like one world was a "giant" world and another world was completely underwater.
I used to really like the game Kid Icarus as well as Punchout. I still play them sometimes on an emulator. I would like to get an oldschool nintendo system some day.
One of my favorite games is also Zelda Skyward sword. I like Link traveling on his bird just as much as when he is on Epona. I can't forget about Mario Kart for the Wii. Rainbow road is my favorite board no matter what version of Mario Kart I'm playing. Though more than anything else, it's the only time I get to throw things at people without getting in trouble,hehe.
Ma favourite game game for Nintendo consoles is Mario Kart. Apart from the fact that I am in love with games that involves racing I like how the developer implemented the gameplay into a game like this and also the multiplayer matches are just amazing to play with, especially with friends. Also I really like the tracks and circuits and the "baloon" mode that can be played, it's very enjoyable.
I don't know if I could pick an absolute favourite. I've loved the pokemon series and the Zelda series. Smash bros is probably my go to game when it comes to multiplayer, but in terms of pure enjoyment, I think I've had more fun with Pokemon than anything else from Nintendo.
Most of the main game series that are known as Nintendo titles are pretty great in my opinion! I don't think there's really any Nintendo game that is well-known and recognized that isn't at least a decent game.
If I chose a favorite though, I'd go with Fire Emblem: Awakening. I loved the versatility of the character in the game, it was like I was really creating my own army. Very fun, and a unique, interesting story, too. The voice acting was also great, both in Japanese and in English. There's not a lot of games I've gotten this much enjoyment out of. I've put hundreds of hours into it too, and I still haven't finished unlocking it all or lost interest in it. Lots of replayability too because you can always experience something new.
Some close seconds, though, would be the Pokemon game series and, of course, the Legend of Zelda series.
