Executive Meddling: Nintendo has had a up and down history with executive meddling. Originally Nintendo did this in the early days of the NES/Famicom to avoid having poor quality games flood its first home console (Nintendo had to later drop this for legal reasons) and to make sure their own 1st and 2nd party games remain high in quality even if it meant 1st/2nd party software droughts at times (which Nintendo still does to this day). Unfortunately Nintendo has been hit hard by executive meddling by many 3rd parties, leading to many 3rd party games either being gimped / badly ported, in poor quality, or not coming out on Nintendo's systems even when Nintendo makes a high-quality and capable system.
Fan Nickname: Brazilians often refer to Nintendo as the Big N, probably thanks to their Nintendo World magazine.
"Ninty" is also commonly used.
Fandom Nod: Nintendo's digital event for E3 2014 contained a lot of references to their fanbase, mostly in the Robot Chicken sketches:
One Straw Fan in the audience complains about the abundance of Mario games, and the lack of Mother 3 and Star Fox, the latter of which is actually getting a new game.
The segment where Link complains about Toon Link being there is a reference to some fans having knee jerk reactions whenever Toon Link appears.
Viral Marketing: Nintendo's approach to marketing in hopes fans will be the ones to spread the word about the latest and upcoming products for Nintendo's systems. Unfortunately many see this as Network Decay since Nintendo no longer markets heavily to the mainstream unlike back in the NES and SNES eras. This lack of mainstream advertising often leads to the result of new IPs commercially failing even if they are critically acclaimed.
