A fact that I never discussed.
The only point I've contended is the notion that lower than expected sales of a game on a console that had already sold 5-6 million is because of low sales of the console, ridiculous point, and the only reason it was brought up was to explain disappointing sales of a game. If PLG was an appealing game in Japan, like Pokemon gen 8 will be, it could have sold double the number.
When Poke 8 releases, Switch will be at 8-10 million sold, so not that much more than now, and the new audience will be about the same, buying Smash, Fire Emblem, NSMB, etc. And you'll see Poke 8 selling 1.5-1.8 million FW, and joining the evergreen group.
Smash doubling PLG's FW sales, coming only a month after it, confirms what I always said. That particular game has an appeal problem in Japan (single player short RPG, fourth remake of said game, short on content, simple graphics, etc). When used games begin flooding Japanese stores, the game will disappear from the charts.
PLG will not join the evergreen group, Smash will.
