These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Nintendo has earned a lot of opinions over the years. Here is a partial list of them.
The late Hiroshi Yamauchi Vs. Satoru Iwata who is the better leader for Nintendo? For Yamauchi he was a brilliant business man and is one of the reasons why the NES and Super NES did so well. However to others Yamauchi is known as the reason why the N64 didn't as well, namely on how due to Yamauchi's controlling nature and is the reason why Nintendo still has trouble with 3rd parties. As for Iwata there are those who praise him for making Nintendo a lot more innovative and a lot more profitable thanks to the Wii and DS. Then there are those who hate Iwata's leadership on how sure Nintendo got a lot more popular again for all the wrong reasons and made Nintendo's games a lot weaker and more casual. (Not too mention on how despite all the profits Nintendo made they still don't have better 3rd party support.)
Even Shigeru Miyamoto is becoming a case of this as while any backlash against him was unheard of for years until The New Tens when people hated what he did with Paper Mario: Sticker Star by trimming out the story and blame him for the Super Mario Bros. franchise for becoming stagnant. While there are still plenty of people who love Shigeru and easily forgive him for a few certain recent issues about him but there are those who wish he would just retire so his frnachises will actually get to change a bit more.
Nintendo's role in ending The Great Video Game Crash of 1983 thanks to the NES, is the idea of Nintendo saving the Video Game Industry with the NES an absolute fact and reason why we should always appreciate Nintendo? Or is Nintendo been given a little too much credit in ending the crash and its not that big a deal? (Those who believe the latter often point out on how the crash was only in the North American game console market as the Computer Industry and the Game Industry in other places such as Japan were just fine at the time.)
Most of the time when Nintendo shows a Nintendo Direct, fans will usually be divided over whether they liked what was shown, or disappointed that they didn't show what they wanted.
The May 20th, 2014 closing of Nintendo Wi-Fi Connection, a service that allowed people to play certain Wii and DS games online. Some of the base understand that the service had to end sometime. The other remaining base fractured greatly, split over numerous things that include, but are not limited to: Seeing this closure as another sign Nintendo is doomed, that Iwata needs to be fired over this closure, this closure being a scam to force people to upgrade to Wii U and 3DS and the Nintendo Network, and people trying to plead to Nintendo to not end Nintendo Wi-Fi connection.
Germans Love David Hasselhoff: North America (specifically, the United States) is by far the largest market for Nintendo games, with particular franchises that are moderately popular in Japan being hugely popular in America (The Legend of Zelda and Metroid being the most notable examples). Even games that are exceedingly popular in Japan still do much better across the Pacific; the first Super Mario Bros. sold an impressive 6.8 million units in Japan, but a whopping 29 million in North America.
Jumping the Shark / Dork Age: Most Fan Dumb and Hate Dumb would agree this started with the Wii in 2006 ushering in casual gaming with motion controllers. The Wii would then collapse in 2010 due to lack of support leading to the 3DS and Wii U being rushed causing those systems to have rocky starts. Also there's the matter of their overprotection of their IPs at times from their American branch. Many critics / Fan Dumb / Hate Dumb call for Nintendo to go 3rd party and/or go mobile, leave the video game industry all together, or just fire Iwata and all senior management (including Miyamoto) in hope new blood would help Nintendo "get with the times" even if any changes are just short term gains with long term risk of failing.
Older Than They Think: The company goes as far back as 1889, when it was just selling hanafuda playing cards. Hanafuda cards still get referenced by the company from time to time, and can be obtained from Club Nintendo in some regions. Also if you think selling Love Hotels count as this.
Then when the GameCube hit, Nintendo was once again painted as "uncool" and "kiddie" due to the system's design and going up against the original XBox and Playstation 2 which had many "hardcore" titles compared to titles for the GameCube though Nintendo would later recover with the Wii despite it's weak architecture and it enjoyed four years of dominance on the market making kid/casual games cool again. Nintendo once again is on the wrong end of popularity by the now infamous Wii U. To sum that up, people just don't know about it or view it as "uncool". Nintendo's lack of mainstream marketing in favor of Viral Marketing doesn't help.
Vindicated by History: Despite the problems with Nintendo Wi-Fi Connection that led many to declare Nintendo's entry to online services to be The Scrappy of the seventh gen, the service's May 20th, 2014 closing has fans trying everything they can to save the service from ending.
