If they don’t actually film it on the Olympic Peninsula they’re doing it wrong.
It’s just such a god damned beautiful area, and with how far apart the small towns are, great fodder for any post-apocalyptic stories.
Further, there’s several large Reservations in the area, I think any post-apocalyptic story set in the area that doesn’t have Native American folklore becoming resurgent due to the local native population is missing a real opportunity for kickass storytelling. Quinalt, Quileute, Maka, Hoh, and Skokomish all surround the Olympic mountains. Ignoring the large local native populations would be foolish, imho.
Probably filmed in Vancouver/south BC cost. The studio infrastructure is already there and lots of very similar landscapes. The game setting has great potential to be a fantastic series. I really hope they lean into the first nations history too!
