I think a lot of HN users, living in our own PC-oriented bubble, may not have realised the world has completely passed PCs by and that smartphones are the personal computers of the current generation. While PS5 and Switch each have about 100-150 million in sales, there are an estimated 3 billion mobile game players. Are a majority of those "mobile game players" playing Flappy Bird, sure. But again, even 10% of that number being interested in "real games" would outnumber PS5 and Switch players combined. Fortnite and PUBG each have hundreds of millions of active users, most are on console but around 20% appear to be on mobile from a quick search. Genshin Impact also has tens of of millions MAU, a non-neglible percentage of which are mobile players. There are hundreds of millions of people for whom being able to play 3D games on their phone matters.
