Bethesda isn't really "big".  EA, Activision and Ubisoft are "big".  They release several big budget titles every year.  Don't expect them to release their biggest budget titles for the Switch when they get released for the PS4 and XB1.  They could do it if they wanted to, but they just don't want to.  For example, Madden has been on platforms much weaker than the Switch for years and years.    It would be ridiculously easy for them to release Madden on Switch if they wanted to.  They just don't want to.

Yes, a 2-D platformer like Megaman who was in Smash 4 will do better on the Switch. I don't think anybody should be surprised by that. In terms of Street Fighter 30th Anniversary, the PS4 version shows "Shipping in 2-4 weeks". I don't know about you, but if I see a game on Amazon that is already released and the shipping estimate shows 2-4 weeks then I'm not likely to make a purchase.

I'm going to quote Symbios most recent post instead of linking since I don't think many people will click the link, and this information is EXTREMELY important to understand regarding 3rd parties interest in the Switch.

What does this show? With Nintendo publishing 11 games on the Switch, about 10% of the total retail games released on the Switch, they have 70% of the total software sales.  That's the reality. On PS4 Sony published games don't have 70% the total software sales.  There is far more parity between first party and third party software sales. The Switch may have a massive userbase but if that userbase only buys Nintendo published games 70% of the time that leaves only 30% for all the other publishers to fight over.

Which is no different than what we are already used, but some people in VGC will deny that the presence and buying of 3rd parties on Nintendo is low. But when others accept is because 3rd party games are bad and Nintendo fans have better taste than other fans.

I see as no surprise that Switch is bought to play Nintendo games, since MP will run better on X1PS4, the platforms are bigger and cheaper to buy.

Switch third party efforts don't need to sell on par with other systems, they just have to be profitable, I would bet Capcom is pretty happy with those Street Fighter and Megaman sales on Switch.

If you look at the eShop rankings there is quite a bit of diversity for people who buy online (which is great for pubs because there's not retailer cutting into their profit), the top 10 isn't just Nintendo games.

At retail for the time being Nintendo will dominate because they've brought big guns to the Switch whereas others haven't, but even then we are seeing third party software doing alright on Switch.

Also no offence to the site, but we know VGChartz numbers can't be taken as gospel, they are estimates.

I completely agree. That's why there will be more ports of old games and new releases of non-graphically intensive games. Or you'll get stuff like Resident Evil 7 Cloud Edition. If the idea is just to push a profit then part of that equation is limiting the amount of resources (time and money) spent on developing Switch software.

Still, releasing 10% of the products and retaining 70% of the marketshare is to much.

I agree, but Madden is a bad example. Madden is EA, and EA and Nintendo are special somehow. I never really saw a good support by EA in recent generations. But Ubisoft and Activision are more neutral to Nintendo (Ubisoft even somewhat positive), and they release some bigger stuff - but by far not all. For instance Ubi has Just Dance, Steep and Mario+Rabbids for Switch, but not Ass Creed. I think porting cost vs. expected sales make this a too hard decision. It might or might not change with a bigger userbase.

Do you have any idea how this could be changed?

There are two reasons for it:

First: Nintendo is an insanely successful game maker.

Second: Most high prolific games aren't releasing on Nintendo platforms.

See, Ubisoft would have much higher sales on Switch, if the had released Destiny, Assassins Creed, For Honor and Far Cry. Because currently these high profile IPs add to the sales for Ubisoft games on Switch... nothing.

You can fairly compare only the games released on all platforms: Just Dance, Fractured but Whole, Doom, Skyrim, Wolfenstein. Many of these are old ports. Hmm, VGC has no data (yet?) for Switch sales of South Park and Wolfenstein. For Skyrim I gfo with the special edition as the release for PS4 and XB1.

So, do 3rd-party games sell worse on Nintendo-platforms? Yes. Is it that bad as painted by the data cited by Meggiddo? No, because that is because many games are not released on Nintendo in the first place. So, the 70% market share is because the other game makers leave the platform to Nintendo. What should Nintendo do? Not release games?

So, these numbers do indeed explain why 3rd-parties are shy to release on Nintendo-platforms. No need to angle for power-explanations or conspiracies or anything. But the dominance of Nintendo-software is because basically so many games are missing on the platform.

We will see more data in the future, with more multi-platform releases like Dark Souls Remastered, Dragon Quest XI and so on.

Square Enix is wrong.
ARM and Maxwell is extremely different to x86 and Graphics Core Next.

The similarities that the Switch and Playstation 4 have is actually on the software side... Both leverage a *nix derived OS, both share common API's like OpenGL and Vulkan.

This. It all comes down to whether it is financially feasible, said feasibility will obviously increase with the more hardware units that have been shifted... To the point where sometimes companies can justify creating a game+game engine almost entirely from scratch to take full advantage of said lower specced machine.

PC gets the majority of Multiplats? Very rarely does the PC miss out on a big AAA multiplatform exclusive.

Well. Yes and no. It has some technical showcases that can't be ignored.
But the main reason why it got a port to the Switch was because it was a 60fps title, there was tons of room to move by cutting that down to 30fps and making some visual concessions elsewhere.

The big strength the Switch has is that from a GPU feature set perspective it is equivalent (And in some aspects exceeds) the Xbox One and Playstation 4... Which is something the WiiU or Wii didn't share.

Flops is a theoretical performance ceiling and not representative of real-world performance.
