The idea of some sort of anti-eastern bias just seems weird to me. I don't have any evidence or convincing argument, I just see a game like Metaphor: Refantazio capture the hearts of so much of the gamers and critics, and it's a freaking jRPG. I have complained (not seriously, just to take the piss) about all the "anime bullshit" in games all over the place. When I think of games I think of Japanese/anime stuff by default now. Genshin Impact more than Call of Duty. Sure it's probably just the media I choose to consume.
But also it's seeing the kids of my relatives and friends with their Japanese animes and games. My niece like drawing and her sketch book is all anime looking stuff- but it's not "foreign" to her, it's the norm (she/we are not Japanese at all, we're collectively American and from a bunch of other cultural backgrounds).
So... I dunno... I'm just so used to Japanese (and Korean) stuff being so culturally dominant in the spaces of animation, games, toys, etc. It feels like when people were calling fantasy "nerd" stuff during the height of Game of Thrones and I was like.. no, it's no longer niche, it's the mainstream.
And then where do things like the Sony games come in- Horizons, Tsushima, Last of Us, etc- non Japanese studios on a Japanese electronics company gaming platform. The world is global, as I like to say, much to my friends' annoyance.
