Yeah. I was about to talk about how good it is that Pokémon Let's Go sales tanked this year, then I saw the Mario Kart 8 number and went like... yeah, okay, no lol. Weird stuff going on with that article.

If the 23 million-sellers thing is actually true, though, it'd be nice to know which games they are.

@curl-6 Your information is wrong.

From page 7:

The results for this fiscal year showed strong software sales for Nintendo Switch, which contributed
to the expansion of hardware sales. In particular, Super Smash Bros. Ultimate recorded sales of 13.81
million units, while Pokémon Let’s Go, Pikachu! and Pokémon Let’s Go, Eevee! sold 10.63 million units
and Super Mario Party sold 6.4 million units, making them all major worldwide hits. In addition, Mario
Kart 8 Deluxe sold 7.47 million units. Combined with steadily-growing sales of titles released during
previous fiscal years and titles released by other software publishers, the total number of million-seller
titles during this fiscal year was 23. As a result, hardware sales for this fiscal year totaled 16.95 million
units (12.7% increase on a year-on-year basis), while 118.55 million software units were sold (86.7%
increase on a year-on-year basis).

So that's not 23 titles that have sold 1m+ over the course of Switch's lifetime so far, but 23 titles that have sold 1m+ copies during the fiscal year April 1st 2018 to March 31st 2019. This means that games that were released before April 1st 2018 started at sales of 0 again, because it's all about sales during a certain 12-month-period.

For those wondering if the 7.47m figure for Mario Kart 8 Deluxe is correct, yes, it is. That's how many copies the game sold during the previous fiscal year.

Almost certainly not. VGC numbers also list 23 million sellers on Switch. I know they're not the most accurate, but I doubt there's enough of them overtracked enough to fit the number of f2p games that would be over a million.

Switch's total software shipments are at 187.52m by March 31st 2019. That's 25 months on the market.

Microsoft stopped to give out any solid sales numbers, so a comparison for this point in a console's life (or a future point) is not available for the Xbox One.

Sony did not announce a total for software when they announced that PS4 hardware had sold through 35.9m units after 25.5 months on the market. Their financial reports don't single out software numbers at this point in time either, so a comparison is not available. Sony announcing their software total is something that they've only done more recently.
