A singleplayer open-world sandbox RPG in the vein of Skyrim, but you have powerful abilities on cooldowns like in MOBAs/Overwatch, command troops like in Mount & Blade/Blood of Steel/Conqueror’s Blade, and can go around conquering cities/developing your own nation culturally/socially/technologically/economically/etc. like Civilization but more open-ended where you can do things like decide actual religious doctrine and encourage specific aesthetics/music/social norms.
Obviously, though, such a game is incredibly ambitious and I don’t think it’ll ever be made, as it takes the most unique and hardest-to-make parts of several other games and then combines them. Still, I’d love to play it.
You’re thinking of collectivism, the actual opposite of individualism. Confucianism isn’t really related and is about finding meaning and cultivating the self, it’s a form of civil religion.
In fact, Confucianism is about self-cultivation and actualization, though in the context of society.
