Ah, since you clarified, robosquirrel, I have to agree. That amount of detail would be hard to achieve. At best they might have x types of building structures and when a planet is randomly generated it will choose one of those types for the buildings. But it still wouldn't be that detailed, you're right.
Infinity is something i've been waiting for my whole life. When it comes out, i sell everything, move to some ****ty southern country with almost no cost of living and play it forever.
