2D mario games. I used to love them as a little kid. But they haven't evolved enough since. IMO so many 2d platformers have surpassed them in all aspects but accessability. I really get no more enjoyment playing through new super mario bros U than I do playing Super Mario World. The tacky motion controls and poorly implemented multiplayer are the only difference.

Second place goes to pokemon. The only reason its not behind 2D mario games is because other than Dragon Quest Monster there aren't really any alternatives to pokemon if you want that style of game. But seriously the stagnigation of this series, specifically the mainline games, makes each new Call of Duty seem fresh. 

Its surprising really, when you consider how much work nintendo puts into some of its other franchises, how lazy they are with their two biggest ones. Heck maybe thats why those two franchises are their biggest. Some people just want more of the same.

Animal Crossing. Not much of a fan.

I don´t like Animal Crossing

Wii party series. For nintendo's proper games I don't believe anything can top them.

I really enjoy most Nintendo franchises I've tried. I do however hate Kirby, I've really tried to like him, but all of his games are just really boring. I don't like the New Super Mario Bros series, except for U, which is fantastic.

I haven't tried Fire Emblem or Animal Crossing yet, but I will be trying them both on my 3DS soon enough.

Fire Emblem. Just don't like it. Advance Wars on the other hand...

Apart from the mindf****** replies (mainly SethNintendoPie), I guess mine would be the top...

Out of all Nintendo franchise that I hate the most was the Donkey Kong franchise, just for the sake it starring DK. That stems from him being the first prime enemy of Mario. I was a full-blown Mario-crack-head during my upbringing, DK was on the top my hate/rage/kill-list, tied with Bowser, just because they were Mario's nemesis, but after having knowledge that DK was coming back in DKC for the SNES, he got cattapulted to the top leaving Bowser way behind.
A friend of mine introduced me to DKC2, thinking it would make me come to terms with DK, however it did not. In fact it made me fueled my rage against the stubborn gorrila even more just because the game was so hard that I died countless of time. Give in mind that I still had a mindset of a "hardcore Mario-fan".
When I acquired the N64, DK was my wipping sapien of choice in the Mario spin-offs. Got Smash Bros. and boy did I let out my frustration on him to the point you would think the character made me gone banana's for his existence. XD
By the time the 6th was going through the half period, I finally come to terms that my hatred towards the big lug was really getting the best of me as a person, at the same time realized my hatred towards the Sony's Playstations and Microsofts Xboxes was doing the same thing...

Looking back on it, I never hated any other franchise other than DK's, I guess when a kid puts his mind on something from his/her early childhood, he/she might really not let it go for a long time and quite possibly never...

out of those the one i like less is Kirby, still like it though
i have never played Pikmin also

I agree

I honestly think that A link to the past isa classic and I would totally understand why an individual would say that it was the best Zelda.

i also understand why you wouldn't recommend Majora to a 1st timer aswell. I usually feel out of place when I tell people thatMajora was my favorite Zelda

Donkey Kong arcade, Mario, Zelda, Metroid, Kirby, and Star Fox are my gaming bread and butter right alongside Halo. I'm a long time Nintendo fan even though my gaming roots started with Atari and Sega.

Animal Crossing doesn't appeal to me at all. Not even a little bit.

I don't play Pokemon or Pikmin, but they have some appeal. Animal Crossing's popularity is a complete mystery to me.
