Will starting locations be spread all over the actual known and inhabitable areas?asked by Hiromatsu

That's a very large phrase, all over. But there will be a lot of different starting locations, at least several, that you get to pick from.

You probably wouldn't be starting in the Banu area.

No. Not the Xi'an area, not the Banu area.

But it will be spread out. We're not going to concentrate all humanity in one area.

No, there are going to be a handful of landing zones at least that you can start with, and that may expand over time.
