Ancient Chinese RPG The Bustling World is, in fact, all of the genres, from city builder to life sim

Yeah, I'm... skeptical, to say the least. I don't think any of these sprawling, massively-scoped "everything games" have ever actually lived up to the hype. It's a problem of pure logistics. Making a game with so many different segments each with entirely unique gameplay loops is essentially like developing more than half a dozen games at once. It's the problem Spore had - the scope was just too broad, and even with EA and Will Wright behind it, it eventually released as a pretty decent creature creator stapled to four shallow, rushed game stages.

No studio has the resources or inclination to commit to the 10-15+ year development cycle for a single game needed to fit that much scope, and even if they did, the entire game design landscape would have changed between the beginning and the end of the project, which would make major technical and design components of the game obsolete before it was even finished.

I'd put money on this game either becoming vaporware or releasing as a chaotic, disjointed mess with the depth of a puddle. I'd love to see them prove me wrong, but I just don't see how anyone could overcome those kinds of logistical hurdles.
