Why exactly? Star fox Zero shouldn't affect that much either way.

What?  No, I was saying Splatoon was the only game recently outside Mario, Zelda, Mario Kart, and Smash to get any marketing worth a penny. 

And even those were mismarketed sometimes.  Not that it was one of their diversification IPs :P.  Diversication would be found in Fire Emblem, Xenoblade, F-Zero, Metroid, Fatal Frame, Golden Sun, even Mother plus 3rd party exclusives and spinoffs like Hyrule Warriors, Bayonetta 2, Wonderful 101, No More Heroes, Last Story, etc.  They own and have worked with 3rd parties to make some decidedly NOT childish games and new IP.  They just never, ever market those worth anything.  If Xenoblade Chronicles X was an upcoming Sony exclusive, they would never let us hear the end of it.  They would show it off everywhere, talk it up, advertise it constantly as release approached.  Nintendo, on the other hand, didn't just not market the first Xenoblade they freaking kneecapped it before sending it west.  Metroid Prime?  That would get the freaking Last of Us treatment; you wouldn't be able to escape that game if Sony or Microsoft were making it.  Problem is, Nintendo spends money making these games (the aforementioned IP and of course third party exclusives like Bayonetta 2 or No More Heroes) and then do exactly nothing to market it.  They have potential for an extremely wide appeal.  They don't because despite having the resources and IP, they seem to think that adults develop telepathy, especially in the west, and don't need to be informed of or sold on anything.

But this conversation isn't really going anywhere and these quote trees are getting ridiculous so let's call this done. :P

Nintendo's never really been great at marketing. The last generation they weren't outmarketed was in the 1980s. 

Xenoblade chronicles does have online with 4 players taking on huge monsters. If thats not cool,, idk what is. Theres nothing like niche, there could be a huge audience for xenoblade chronicles X. WHat makes other games less niche than others? just because they were more popular in the start? idk what you guys are talking about niche, but if some random person just sees a trailer of this game and he think it looks awsome, then he goes and buys it. What makes it so niche. So all final fantasies are also niche games then? and fire emblem too?

Marketing is very very expensive, sometimes more expensive than making a game if you really want a huge marketing. Nintendo has been smart about marketing sometimes and sometimes not, but i seen more marketing to splatoon and super mario maker, so thats good. Lets hope nintendo markets the fuck out of xenoblade chronicles X, more than mario kart 8 and splatoon combined

Sales. Most JRPGs are niche by default. The only current ones that aren't niche that I can think of off the top of my head are Pokemon, Final Fantasy and Dragon Quest.

Monster Hunter too.
And I'm hopeful that Fire Emblem can get to that point as well. Since Awakening is closing in on 2 million and Fates is expected to exceed the amount that Awakening may finish with.

Uh, no Nintendo was great at marketing once upon a time.  The N64 marketing campaign was very, very strong early on (Get N or Get Out being the most memorable and prolific ad and epitomized how you reach out the young while not alienating the old), which is why it had a very strong start.  The lack of 3rd party support, cost of games, and game droughts (all mostly due to cartridge nonsense) led to the legs dropping off but the marketing was on point.  The Super Nintendo had a large number of ads.  The slogan "Now Your Playing with Power, SUPER Power!" was quite widespread and of course the Super Mario World ad was a major push many remember to this day.  The marketing blunders of Nintendo started with Gamecube, where they did piss all to market that thing (I watched Cartoon Network all the time growing up and only knew Super Mario Sunshine launched because Toonami reviewed it months after release).  The Wii saw a revival in Nintendo marketing, with the "Wii Would Like to Play" ad campaign being very well done and wide spread all the way through 2008, advertising Mario Sunshine, Smash Bros, Red Steel, Wii Sports,Mario Kart, Legend of Zelda Twilight Princess (which got two other, seperate ads that were quite prolific), and even Metroid Prime 3 (though the ad was very rare to see).  It was late 2009 - 2010 when their marketing took a nose dive from "competent" (where it had fallen to) to "non existent," (they went from marketing nearly every exclusive to launching Skyward Sword, Xenoblade, Last Story, Mario Party 9, and Pandora's Tower without a word essentiall) where it remained until the Wii U's uninformative launch ad and it only went downhill from there until they woke up in time to market Mario Kart 8 over 1.5 years later.  Nintendo were great at marketing for a long while and then...well then I don't know what.  They just up and gave up.  And it's something they must fix.  Marketing isn't a good helper, it is essential.  Those who don't market, don't succeed.  That's just a foundational principle of good business.

I wonder if this is a reaction to the feedback they seemed to be getting. Not a bad move if so.

Yeah it would be great one for wii u and another one for nx with improvements like 1080p
