2017, namely in the last quarter of the year. But even then, there was stuff earlier as well.
-Super Mario Odyssey
-Zelda: Breath of the Wild
-Stardew Valley
-Skyrim
-Xenoblade Chronicles 2
-Mario Kart 8 Deluxe
-Free Online
And there are other first-party games I didn't mention. 2017 had a lot of ports (as every year for Switch has), but that's not inherently a bad thing.
2019 would be the runner-up, followed by 2022. 2018, 2020, and 2021 are all pretty interchangeable off the top of my head as far as the weakest years go, maybe 2018 at the bottom for introducing paid online and having little I cared about other than Smash.
2023 will probably be right around the middle. I am going to get FE Engage and Zelda: Tears of the Kingdom at some point.
