You can do really complex and interesting stuff with procedural generation, even at-scale. You need a large breadth of well-designed rules, and then you need temporal simulation over that breadth. That simulated history is just as important as having a lot of high quality rules when you want to create a living, breathing world. Ultima Ratio Regum is an example of how important this time aspect really is, that a place needs to have a history.

The real limitation is that virtual worlds get boring. It really doesn't matter how sophisticated they are. Generative AI can't help with that. It's not a problem of the structure, or needing some additional variety, or more sophisticated set of constraints. It's the simple fact that while you can day dream about endlessly flying around a galaxy, landing on planets, eventually it just becomes rote. It's a normal biological process of adaptation and normalization. Like how when you first move somewhere, everything is fresh and full of potential, and then 3 years on everything that was novel and cool has become just background noise.

Dwarf Fortress also does an excellent job of this
