I thought it would be a good idea to size up different companies and their support for the Switch so far. To see who is talking big and who is giving actual suppport.

This list is probably incomplete, so if I miss things or have them wrong, please mention it so I can add/correct things. Also mention if you want this updated or it is OK as a one-time thing.

As game isn't the same as another game, I mark some things with formatting. Here is what I use:

• million-seller on Switch
  
• Nintendo-exclusive
• no physical release (if only physical in some region aka Okami only in japan it is also italic)
  
• (limited release) (only cloud or japan-only)

I list already released games and announcements separately.

So, let's get to it.

EDIT: Formatting turned not out as I intended, so sorry for the mess.

Ubisoft

Ubisoft is for years the strongest supporter of Nintendo platforms. Also with Switch they brought some games.

Take 2 Interactive/2K Games/Rockstar

Take Two usually have a spotty support for Nintendo devices. Their subsidiary Rockstar very seldomly releases stuff for Nintendo. How does it look for Switch?

Bethesda/id soft

Bethesda usually is a no-show on Nintendo-consoles. With their Switch-support they surprised.

EA

EA had an "unprecedented partnership" with Nintendo at the time of the WiiU. How does it look for Switch?

Activision/Blizzard

Blizzard took it's sweet time with Diablo.

THQ Nordic/Koch Media/Deep Silver

THQ Nordic had pretty regular releases on Switch.

Bandai Namco

Bandai Namco has a pretty good relationship with Nintendo lately in my opinion.

Capcom

Capcom as a japanese company is also releasing quite some stuff for Switch.

Sega/Atlus

Sonic is by now a pretty stable occurence on Nintendo consoles, Switch is no different.

NIS/NISA

NIS porting over their catalog to Switch.

Square Enix

Square Enix was a classic partner of Nintendo, but switched to Playstation as it came out. In the last year Nintendo and Square mended their relationship a bit.

Koei Tecmo

Koei Tecmo is putting out also a lot of fine games.

Think you are missing a few Techno-Koie games.

Your list isn't updated. NBA 2K19 is released, Steep is cancelled and The Stick Of Truth is already out. And so is the Capcom BTU Bundle, and Fifa 19 which is out since today.

And Fear Effect Sedna isn't a Square Enix game, it's a Sushee/Forever Entertainement game

Which ones? I can add them.

Steep is cancelled? Didn't knew that. Thanks for your hints, I fix it.

Oh, a lot of japanese only releases, but yes, I missed them.

Didn't Ubisoft announce many Hasbro tabletop games coming to the Switch, like Risk and others?

EA, obviously!

Ha ha, actually, I am happiest with Capcom, though Koei and Square are really good too. I would also give a shout out to Bethesda, they're smaller than many of the others and cranked their support from 0 to 90 this gen.

A few not yet mentioned

Ubisoft:
Sports Party [retail]
Legendary Fishing [retail]

THQ:
Pillars of Eternity II: Deadfire [retail]

Capcom:
Onimusha remaster[retail Japan I believe]

Sega:
Puyo Puyo Tetris
Valkyria Chronicles 1
Sega Mega Drive Classics

I think there's more those were just from the top of my head

Bethesda has been pretty great so far.

I'll be happy with Namco if they bring future Tales of to the system. Tecmo with Gust Co. titles. 

Sega has some cool stuff that isn't Sanic, hoping SMT regains that magic from their 16 bit days and 6th gen.

Capcom has some IPs I care about, so no much way around avoiding them.

Square, just keep bringing the Dragon Quest stuff.
