Me personally have not played any new Nintendo games since around 2015 when I traded in my Wii U. I might buy a Switch later on when it's cheaper but I just do not see me playing a lot of Nintendo games. I prefer Sony games. After the Wii U I think of Nintendo as a great developer but will always do their games with little or no story at all. I enjoy great stories and graphics.

Define "many".I usually buy Nintendo home consoles, as I have since the N64, but I never own many games for them. I bought the Switch at launch and I have bought 3 games with a 4th currently on its way. I haven't finished either of them. So far I got about as much out of the console as I expected. I'm sure at the end of this gen I will not have bought more than 10 games for the Switch.

My reason is that it's not my main platform and I generally do not enjoy using it. But it has certain games I won't be able to experience anywhere else so I will have to put up with it.

Wow, you 3 wrote all the reasons that I'd answer here.

I enjoyed Wii, but Wii U was a disgrace for me. NSW for me is just handheld, which is ok but I don't have many games to play there. I'm trying to make a top 10, but I'm struggling. Since Wii and DS, I've been wanting Nintendo just for Mario, MK, Pokemon, Fire Emblem, Zelda. However, since Wii U, I'm not really keen on Mario and MK anymore. MK8 is brilliant but it's still the same thing over and over again.

Nintendo's also too expensive, their consoles have been lacking all the standard online features that others have and Wii U was a waste of money for me (to be honest, currently I'm enjoying some VC games on it, so Wii U ended up being worth it for me, but not when I early adopted it).

I also don't care about retro games and all those hundreds of indie 2D plats that come out for Nintendo.

all nintendo for NES and SNES, 64, gamecube. had a nintendo power sub, got the special order form for the golden n64 cartridge of Ocarina of time, and it came with a strategy guide by nintendo, when it finally got to the house, i had some friends come home from middle school wanting to see it. that was so fun and will never be forgotten.

Back in the day when saved points were not around yet. You were lucky to have pause but that was about as close as it got for years.

some things that come to mind for those nintendo systems are: Super Mario series, Zelda games, DK country series, Sim city, sim ant, contra, street fighter II, Jackal, Turok 2 had great couch death match with 4 controller support on N64, punch out, yoshi island, just my go to for many years until gamecube.

Nintendo always had the best hardware as far as longevity besides some dusty old carts. the consoles were solid and lasted and still last for years.

The wii was fun but it was fun with the wii sports, nothing else really resonated with me outside of mario galaxy, mg2. the wii u was ok, for the nintendo games, but nothing pops out at me at the moment typing this.

I still have my virtual boy packed away, many hours and hurting eyes playing that! though probably not in over 15 years since I have set it up and turned it on.

Tons of nostalgia, for the beginning of nintendo and years afterwards, just as I have gotten older, I have really embraced xbox and playstion brands. while the newer stuff just isnt resonating with me like in the past. I would love to relive that excitement with them, that is why I get so down sometimes about what they offer.

I've been playing Nintendo games since before they had a console to put them on. I had Donkey Kong and Donkey Kong Jr. on Colecovision when I was a kid. Got an NES in 1989. And, there hasn't been a year since that I didn't play a Nintendo game on one of their consoles or handhelds. The only thing I skipped was the Virtual Boy.

I'm just not interested in the kind of games that are on nintendo consoles. Everything from the theme, aesthetics, tone, plot and the general genres are off putting to me. Also, there's hardly any third-party party support even from the Japanese devs to offset the lack of interesting first-party games for me. I mainly play alot of rpgs, tactical, Japanese games with mature themes.

As someone who have always played on different platforms (including Sega at the time) overall I think Nintendo is my favourite "big" publisher/developer and that's basically beacuse I think they are the most skilled at game design - and with that I mean core gameplay loop, game feel and level design.

That said I think they have some great issues as well: mainly too often their games lack ambition, too often they're afraid to challange the player, plus some of their commercial policies are dumb and stubborn.

I only play Fire Emblem and Xenoblade. I'm not interested in most Nintendo franchises because they seem a lot too childish to me now.
There are other reasons, but I'd rather not state them. Acevil is watching me...

Nothing Nintendo has grabbed my interest after the N64. Their policies and focus on casuals is not my thing i guess.
