There are a few great Chinese single player games out there like amazing cultivation simulator, but they are all indie games. The Chinese government restricted how Steam works in China so I have no idea how indie Chinese games are getting out there, if at all.

I played a little Genshin after it first released but was put off by the underage characters being portrayed sexually. The sad fact of the matter is that its a great game made with passion, and many Chinese games have a """lolicon""" issue. I tried the game Mahjong soul after getting into Mahjong from Final Fantasy, and it has the same issue.
And when I say """lolicon"", I mean kids as young as 11-13, maybe even younger. it's disgusting. Otakus seems to run the industry there as far as I can tell, or at least what makes it to the west because to know real stuff about Chinese culture you have to be at least kinda a weeb for Chinese stuff. I got into Xianxia from my love of manga which lead to Manhua. The Xianxia scene has a lot of problems but """lolicon""" hasn't been one of them.
TL;DR The chinese video game industry is run by otakus, at least for whats made it into the west.
