Have you played Expedition 33 yet? That game is dripping French culture in every fibre of its being. What separates it though from recent Chinese content like WuKong and Nezha 2, is that the French culture is still made accessible for a global audience. Black Myth Wukong's story for example is basically incomprehensible for people who don't have a scholar's knowledge of Journey to the West or Buddhist mythology, same with Nezha 2 to an extent.
The problem is that the incomprehensibility is what a lot of Chinese cultural chauvanists like, since they claim Chinese culture after being maligned for so long deserves to be portrayed in an unadultered form. But with how dense Chinese culture is and how the world still has little exposure to it, I don't think putting different coats of paint on it to make it palatable just like the gacha companies, do is in anyway bad. But as always, with a market of China's size if creatives can make bank in China alone the need to appeal to foreign audiences has never been there.
You're right, while E33 is heavily dipped in french culture it was in a highly accessible format. With themes and story that was not spoon fed to the player while still being easily understandable, the french influence is just a coat of paint and can be readily switched out to tell the same story.
For black myth, the game is so deep into Chinese mythology, it is basically incomprehensible to the average gamer. My friends complain about the amount of idioms randomly thrown in instead of speaking plainly. It gets to a point where it starts feeling like story writer is being pretentious. I have the same complaint about other souls game where you need an hour long YouTube video to comprehend the story.
I understand that this is a core part of Chinese literature and it is not targeted towards foreigners to begin with, but surely there must be more to Chinese creatives than just rehashing a 500 year old book.
For the record, I find Chinese games that stand on its own excellent (my time series, Dyson sphere program, heck even marvel rivals)
