What games have what you’d call really good worldbuilding, and what in particular do you like about them?
https://en.wikipedia.org/wiki/Worldbuilding
Worldbuilding is the process of constructing an imaginary world or setting, sometimes associated with a fictional universe. Developing the world with coherent qualities such as a history, geography, culture and ecology is a key task for many science fiction or fantasy writers. Worldbuilding often involves the creation of geography, a backstory, flora, fauna, inhabitants, technology, and often if writing speculative fiction, different peoples. This may include social customs as well as invented languages (often called conlangs) for the world.
Mass Effect completely blew me away when it came out. Loved the overall lore about the Reaper threat and how the different species were connected to each other.
Horizon: Zero Dawn was also great in that regard, and the world felt really well put together, even though the lore wasn’t quite as deep.
