Where Winds Meet had very little marketing too, but through word of mouth ended up becoming a fairly solid hit in the West. I wrote this when the game came out in the other thread, but can repeat it here. It's all about the level of people's exposure to certain aspects of Chinese culture. Westerners already got their first taste of Wuxia 2 decades ago with Crouching Tiger Hidden Dragon and Zhang Yimou's movies, combine that with C-Dramas, web novels, and cultivation donghuas, there's already a niche audience there for the genre. But more importantly even if Westerners don't follow that stuff, its not exactly alien to them, so when they heard WWM was a pretty solid F2P game they figured why not.
In contrast, Western audiences have had literally zero exposure to Chinese myth up to our current times. Shit, the closest maybe is the Kung Fu Panda film franchise haha. Black Myth Wukong was most people's introduction to Chinese myth and tbh, even if that game had fun gameplay and beautiful environments it did not make JTTW palatable to Western audiences at all. Nezha is kind of similar in that on top of most Westerners never having seen the first one, that franchise isn't exactly friendly to people who don't already have a background understanding of Chinese myth. But as always, as more of this stuff comes out, you'll get the niche audience first and finally a fanbase to the point where even if people don't follow it per se, they'll no longer think of it as alien so if a good IP comes out in that genre they'll be open to trying it out.
It's not really about cultural exposure; but industry exposure.
Why did Western gamers pay attention to Where Winds Meet? Because of Genshin. I'm not joking. Chinese gaming is on the map today largely due to the viral effect created by Genshin's astronomical success during the lock downs on a generation (or two) of Western gamers.
If you ask typical Western gamers what Chinese games they know of, chances are they will say Genshin, at least that's my experience and it's clearly the gate way drug for them into Chinese gaming.
Once Genshin went viral, they started paying attention to Chinese games, and now every new Chinese game releases gets some level of recognition and hype (even if Western games are still preferred), and that effect starts snow balling - Black Myth Wukong, Wuthering Waves, Marvel Rivals, Delta Force, Where Wind Meets, Phantom Blade Zero, etc. Combined with active influencer / marketing by Chinese companies, it's starting to have a real effect on the industry.
But with movies, when was the last time there was a block buster release from China in US theaters? There's no hype around Chinese movies in the West. No marketing. Influences are not talking about it. Nezha didn't even bother with an English dub on release - there's just no exposure, so it's not particularly surprising that Chinese movies are ignored in the West.
Also, I think many of the executives leading Chinese film studios are dinosaurs. Not at all like the young, ambitious, and globally aware executives leading Chinese gaming companies (particularly the newer companies like Mihoyo, Kuro, Hypergryph, etc.) They wouldn't know how to market to contemporary Western generations even if they wanted to. That's just a generational gap.
