I glossed over nothing. You're creating your own argument I never made, I said the best selling titles were of the portable reality overall and they are, it's completely lopsided, either handheld games or iterations or handheld variations of usually consoles games using handheld mechanics, which you saw with the DS, the 3DS, the PSP, and the Vita. There's this very strange attempt to act as if the Switch is competing with Xbox and PS when it doesn't, it does have games that are effectively console games, and some work even better when docked than undocked arguably, doesn't change the fact that the handheld focused or modified software isn't the dominant of hardware sales, especially recently if you exclude older releases.
What do you mean by "using handheld mechanics"?
Here's the list of top-selling games for Switch. You will see it's heavily lopsided but not in any way that you described.
1. Mario Kart 8 Deluxe 46.82 million (home console)
2. Animal Crossing: New Horizons 39.38 million (home console)
3. Super Smash Bros Ultimate 28.82 million (home console)
4. Breath of the Wild 27.14 million (home console)
5. Pokemon Sw&Sh 24.50 million (handheld)
6. Super Mario Odyssey (home console)
7. Super Mario Party 18.06 million (home console / no handheld)
8. Pokemon BD&BP 14.79 million (handheld)
9. Pokemon Let's Go 14.66 million (handheld)
10. Ring Fit Adventure 14.54 million (home console / no handheld)
11. New Super Mario Bros U Deluxe 13.31 million (home console)
12. Splatoon 2 13.30 million (home console)
13. Pokemon Legends: Arceus 12.64 million (handheld)
14. Luigi's Mansion 3 11.43 million (home console)
15. Super Mario 3D World + Bowser 9.43 million (home console)
16. Super Mario 3D All-Stars 9.01 million (home console)
17. Monster Hunter Rise 7.70 million (handheld)
18. Super Mario Maker 2 7.15 million (home console)
19. Mario Party Superstars 6.88 million (home console / no handheld)
20. LoZ: Link's Awakening 5.49 million (handheld)
I could even keep going, but just from the top 20 I count 14 top sellers that are traditionally Nintendo home console games. 3 of those have no handheld mode. What is this "of the portable reality" that you claimed? If you're talking about there having been handheld iterations of some of these games, that doesn't make them portable games suddenly, because the DS/3DS became a place where some home console games would play. Everything labeled above as home console is a game that launched for home console or is a present iteration of a home console game.
Anyway, Nintendo Switch is Nintendo's home for their
home console games. They even make top-selling software that can only be played in docked or tabletop mode (ie. no handheld).
