2017 was Switch's best year so far.  However, 2022 is looking even better based on first party content alone.  (And of course in third party content, 2022 is far, far better.)  The only really big 2017 game that doesn't have a 2022 analogue is Mario Odyssey.  However, I think PLA is about equivalent to that, at least in the sales department.  Also, Switch Sports  >>>>> 1-2 Switch.  On top of all that Nintendo has Bayonetta 3, Kirby, and Mario Strikers and there will be more games announced at E3.  Sure 2017 had more ports, but I'd rather have new games than ports.

In short, 2022 > 2017.

Both are 3D platformers from Nintendo. Kirby is the most reasonable comparison to go for Mario Odyssey. 

Advance Wars is not as big as you think, I left it out for a reason. I didn’t forget Arceus. It already released and I mentioned it in the OP when I posted this. 

Never thought about that. The games released/releasing really look comparable. 2017 was the best launch year of any console, but 2022 could really top it.

Just Bayonetta 3 for me. My Switch hasn't been used in a good year or two. Actually, scratch that, I haven't touched my Switch since Astral Chain. So 3 years give or take.

2023 will for sure be quieter than this crazy year, but I don't think it'll be that quiet.

A realistic 2023 I could see 2D Mario, Pokemon game, MP4, DK game, maybe more Prime series remakes if the first one is this year, maybe WW/TP HD, maybe something like Star Fox or pikmin 4 or something, and a lot of third party stuff. That would still be a heavy year 

I though you were making the argument that 2022 might actually top 2017 for Switch. It is a compelling argument when you had in Pokemon Legends: Arceus and all the 2022 releases.  

I haven’t given up hope of Pikmin 4 coming out this year, but it might end up being a crowded schedule.

Personally I felt the Switch's 2017 lineup to be pointless if you were a WiiU owner.
Breath of the Wild and Mario Kart 8 being prime examples of "must haves" that were ported, so for me (Even though I bought Switch copies) I had already played these games extensively on the last generation Nintendo console.

But after that... Links Awakening and Metroid Dread have been my favorite titles so far for the platform. Even if Links Awakening is a remake and thus not a "true" exclusive.
Not allot of games have kept me invested where I didn't want to put the console down, might be a sign of changing tastes for me.

Also Silksong is listed for 2022

E3 will be the first time I am expecting to see Silksong so I guess it will be fun to join you all with our shared disappointment if it doesn’t appear.
