SupermetalDave made a comment or so about this and I have to wonder about it. 

While his point that building install base with 1st party to set up for 3rd party does have issues that may have issues, but at the same time I can't help but ask the question. 

What other option did Nintendo have? 

Outside of throwing millions at EA and such, I can't think of any other manner of trying to establish the system as strong other than the first party push they'd been doing. Plus I do feel it is worth noting that three of the 1st party tied games are co-ops with third parties: Mario + Rabbids, Pokken DX, and Fire Emblem Warriors. 

Even with Metaldave's points, I still feel that the strategy was the best they had avaliable, even with the problems that do still linger.

Pretty much, unless Nintendo went out and fully funded a bunch of AAA million dollar third party projects, it was either build up an install base with a lot of 1st party content or have system which lacked both 3rd party and 1st party.

Nintendo's best chance at getting 3rd party support is with a large install base, and their best chance at getting that is with really popular 1st party games like Mario, Zelda and Pokémon.

Basically that what Nintendo is doing with 1st party now is their Wii U strategy, it failed then and is failing now, and that Nintendo is going to start releasing Amiibo Festival esc games in the next year or two.

None that make sense. 

Yes, this is obviously correct.  Funding third party AAA or making it in house is essentially the same thing.

I'm not aware that anyone says they need parity.  But, it is a stone cold fact that gamers that only want, or can only afford to own one console are more likely to choose XB or PS, because of the larger variety of games, and the fact that the mega-blockbusters like CoD are not available on Nintendo consoles.  So, the more third party content they get, the more single-console buyers will choose Nintendo.  

...he's either so full of salt that he's in danger of being mummified or he's an idiot because he's not thinking rationally when it comes to the Switch.  He really, really has to get over the fact that the Switch isn't the AMD Polaris powered 4TFlop traditional console he was hoping it would be.  I was salty too when the Switch was first revealed but I got over it after a couple of weeks and got fully on board before the January Switch presentation.  Then again, it was probably easier for me considering I didn't publicly embarrass myself like he did by arrogantly proclaiming that the Switch would be powered by Polaris over and over again before the reveal.

It leads to better outcomes for both.

Even for as well as Switch is doing now, Pokken DX is going to sell better than if Tekken 7 came to Switch.

Publishers frequently only have only so much capacity to bring games to Switch. They might as well make something special that caters to the tastes of Nintendo fans rather than assume they're exactly the same as PS/Xbox users.

The mulitplats on Switch are nice if and when we get them, but I personally prefer direct collaboration rather than throwaway ports.

The only way Nintendo pulls full third-party support back into their ecosystem is to create a favorable environment for that market, one that can't be ignored.

As it stands right now, publishers like EA and Ubisoft have very little reason to put all their products on Nintendo platforms. Why would they? They already have three platforms to worry about. Why develop a fourth platform and split development and marketing costs even further? The more cost efficient method would be to consolidate your audiences as much as possible--or, at least, use the existing consolidation to your advantage.

So, really, "third-parties" as a generalized group have little reason to alter the situation.

That means Nintendo would have to take the initiative. It's their platform and their responsibility. Of course, that would take a lot of time and money. They'd have to carve that market out by either developing games that are similar to those on other systems, by buying third-party exclusives, by contracting third-parties to develop first-party games, or by a combination of those methods. If they created a demand, supply would eventually fill that void.

I don't see Nintendo going that far, though. Rather, I think they're more interested in replicating the success third-parties have had in other genres with their own first-party work. That way they can have things like "shooters" and "fighting games" on their system while making all the profit on the software.

Hopefully third parties are starting on games now that they know Switch will be very popular. It does make more sense for them to put AAA games they know will sell well on ps4/xbox/pc with one version of the game rather than create a less graphically intense version and add Switch into the mix because that would probably make it sell less on the other systems.
But I gotta think that with Switch's massive success and the huge opportunity for third parties to make boatloads of cash on the Switch's future install base, I would think that third parties will start supporting it well considering that they can spend a lot less money on Switch games because they don't have to put so many man-hours into making super realistic graphics and textures as they would for a ps4/xbox game. They can make an awesome looking game on the Switch for a lot less money, and sell millions, meaning profits would be higher. I think right now third parties are just afraid to compete with Nintendo. I mean Nintendo is the best software studio in the world and third parties have to compete with them on their own system, while third parties have mostly abandoned Nintendo systems for a couple generations so Nintendo buyers are used to buying mostly Nintendo games. Third parties have dug themselves a hole, but their is plenty of money to be made there, I really hope them embrace it and start putting AAA games on Switch. I don't just want to be playing Nintendo games on the Switch!

Nintendo could also talk more to publishers and get deals for at least get porting of some noteworthy games and with they selling healthy they could show how viable the platform is and them publishers wouldn't need as much incentive anymore. Relationships take time to make and Nintendo never showed much interest in that on the latest gens.

Slow down... you consider Nintendo the best studio... if the market itself considered it, WiiU wouldn't be where it is.

And unless Nintendo really pay a lot, there is no reason for them to put out an exclusive for Switch just because "it would cost less"... PS4+X1+PC userbase and general buying offset the gains from new console from Nintendo at less demanding development.
