By making more M-rated games. People want violence, blood, sex and over-the-top mayhem.

Oh sorry for the misunderstanding,i do think the hardware userbase mostly ties with games on the system or expected on it.

They need more variety. Most of their games are E or E10+ and although there's nothing wrong with that, they need to realize that there's more than just their main demographic to appeal to. Also they need to experiment a little with their well known franchises and try to spice them up a little.

Their games are huge. I don't know what you are on about. Mario still sells at an immense attach rate many series wish they had. Zelda was always a more moderate sucess, but still very sucessful.

Mario maker, smash, splatoon have all had quite a favorable acceptance amongst all audiences.

I really have no idea where this is coming from. Its not the first thread i've seen lately with such outlandish notions.

Oh... do you mean how will they target a mature audience? Well... i'm not sure they want to. But bayonetta and devil's third were efforts in that regard.

Of course library plays a major role, but it certainly would've helped if they didn't do things like have a gamepad with a screen that forced the price of the Wii U up by a lot :-/

I mean, the Wii U could probably have been nearly 100$ cheaper if it hadn't had the gamepad, and at that point I believe the Wii U could've sold okayish numbers, which in turn would've given a boost to Wii U software.

I guess it terms of ESRB rating they aren't extremely diverse, like you said most of their games are E & E10+, however they do have some T mixed in there (Fire Emblem, Xenoblade, Zelda, Metroid) and they do publish some M games (Bayonetta, Fatal Frame, Devil's Third).

They are very diverse when it comes to genres though, they make platformers, racing, fighting, turn-based strategy, real-time strategy, turn-based RPG, action RPG, 3rd person shooter, puzzle, party/minigame, rhythm based, various types of simulators, action/adventure, sports.

But those old gens also had pretty decent or strong 3rd party support.  WHen people knew they had more than 2 core franchises to play they comitted to the console. 

Its like this pretty much everone buys Nintendo for their games.

But then yo need the3rd party games to cater to different tastes of people. Nintendo games alone will not justify a spending for someone $400 when they got about 10x more games to pick from and to buy on the competition's console.

I'm a huge Nintendo fan but that's very inaccurate. I was a kid in the 80's and SMB3 was as big as COD. Everyone, everywhere, had to own that game. Mario is no where near the cultural phenomenon it once was. 

They're already big, but, sure, not as big as they used to be. I think that the strategy they'll probably follow is to strengthen the Nintendo brand and expand it to another businesses (mobile games, thematic parks, maybe some animes, social apps like Miitomo...). And, if they use all of this right, they could advertise their franchises and consoles. And I feel that's the right strategy to go, combined with good NX marketing. But it's really impossible to know how it will turn out to be.

I've already said this to someone else, but "ever" might've been a bit hyperbole. As big as ever post-SNES days might be more accurate. :-3
