This doesn't need to get attention internationally to be a mega hit. Just like Nezha 2, if done well, a Chinese WWII FPS can easily sell as well as Black Myth Wukong just with the domestic market.
Creatives really need to focus on what players want instead of what they want. Look at Detective Chinatown 1900; the movie is patriotic slop, but still sold massively well due to knowing what viewers want.
Lenzee's Wuchang this year was very frustrating, because they were so close to a massive hit but the main creative was too focused in his End of Ming Sichuan setting and pissed off the audience. If he set it in the similar End-of-Ming Koxinga Formosa, it would have been a Wukong-level hit.
