Usually the more abstract, the more worldbuilding it is. The Village has it, you get to shape a world through biomes and architecture. I just like to go deeper.
I can't remember the name of that one CYOA where you were the guardian of a land you were to create, got to choose races that live there, the land itself, its riches, technology and magic.
Stuff of this sort. The ideal would be a multiplayer experience.
