@Kevember OK, if you insist on going on... Let us be a little more generous (and honest, seeing as you didn’t count certain games) and count exclusives (as you have already put Octopath Traveler and Mario+Rabbids on the list) and first party games. But I will go a little further than that (but I will explain my reasoning, so don’t worry).

March 2017:

Breath of the Wild (released the same day as the Wii U version, therefore not a port, so while not console exclusive, I count it as new - it’s more synonymous with the Switch anyway) - new

1-2-Switch - new

April 2017:

Mario Kart 8 Deluxe - port (Wii U)

May 2017:

ARMS - new

June 2017:

July 2017:

Splatoon 2 - new

August 2017:

Mario+Rabbids Kingdom Battle (third party exclusive) - new

September 2017:

Pokken Tournament - port (Wii U)

October 2017:

Fire Emblem Warriors (not console exclusive as it also was released on 3DS, but it was simultaneously and the Switch version sold a lot more - anyway, it should be counted as a new game) - new

Super Mario Odyssey - new

November 2017:

Snipperclips Plus - new

December 2017:

Xenoblade Chronicles 2 - new

January 2018:

February 2018:

Bayonetta 1 + 2 - port (Wii U)

March 2018:

Kirby: Star Allies - new

April 2018:

Nintendo LABO - new

May 2018:

Donkey Kong Country: Tropical Freeze - port (Wii U)

Hyrule Warriors - port (combined content from Wii U and 3DS versions)

June 2018:

Mario Tennis Aces - new

Sushi Striker (also a case of simultaneous release on Switch/3DS, but it’s nontheless a new game) - new

July 2018:

Captain Toad - port (Wii U)

Octopath Traveler (third party exclusive) - new

August 2018:

Monster Hunter Generations Ultimate (seeing as this previously only was released in Japan, it could be considered new here in the West, but let us be fair and call it a port) - port (3DS)

September 2018:

Xenoblade Chronicles 2: Torna (could be dismissed as just an expansion, but it’s a full game in itself so we could count it as new) - ”new”

October 2018:

Super Mario Party - new

The World Ends With You: Final Remix (could be considered new as it’s been remade for the Switch - it’s not just a straight up port, but OK, we can call it half new/half port) - new/port (DS)

November 2018:

Pokemon Let's Go - new

Civilization VI (third party console exclusive) - kinda port/kinda new

Starlink: Battle for Atlas (third party, not exclusive, but released simultaneously as other versions, with exclusive Nintendo content, so I put it here) - new, not exclusive, but with exclusive content

December 2018:

Super Smash Bros. Ultimate - new

So... what do we got between March 2017-December 2018?

13 new games. (Add LABO and it’s 14. Add BotW and it’s 15. Add Fire Emblem Warriors, Sushi Striker and Starlink and you got 18. Add XC2: Torna and it’s 19. Add Civ VI and it’s 20. Add TWEWY and it’s 21.)

7 ports. (Count Civ VI and TWEWY as ports and you got 9. Count BotW as a port and you get 10.)

So many ports... So few new games...

Oh and regarding the evidence stuff... At least I say it’s what I think. You on the other hand stated that ”Nintendo has been putting out all of these ports instead of new games”. What we can see is that the Switch has got both new and exclusive games AND ports. I can’t see how the ports have stopped the release of new games, as new games have been released. And if you take away the ports, would there be new games taking their place? I don’t think so. While ports are easy to make, new games takes time to develop. It’s one thing if you rush out new games, but that’s usually not Nintendo’s tactic. Even lesser games like Sushi Striker or Mario Tennis contains a high level of polish. If one enjoy the games or not is beside the point, that is just subjective.

Edit: I count games released simultaneously on several platforms as new to the Switch, just the same way as I for example would count Red Dead Redemption 2 as a new game for the Xbox One, though it also was released on PS4 at the same day. Therefore Fire Emblem Warriors is a new game.

Edit 2: Sorry for the fanboy shill, Kevember. I hope you still have read my PR talk. I just want to add that the games we’re talking about above aren’t the only games worth talking about for the Switch. We also got a lot of great indies and third party support. Not exclusive stuff and some of it’s older, but not everything has to be new or exclusive to be enjoyable. And let us now look forward to 2019: some ports are coming, but also a lot of new and exciting games, on a lot of platforms. Let us enjoy that!
