Couldn’t tell you what the oldest building in my city is, but I assume it’s either an old house in what I assume is the historic district. That, or the clocktower in the downtown park that was once part of a transcontinental railway station.
On a couple side notes, I know I did a class field trip in elementary school to one of the old buildings (don’t remember much about it besides a service elevator that if I recall was just held by rope and wasn’t electric), which compared to other places in America is nothing considering I found out my city was founded around 1881. Can’t say I approve of the part where they fought the natives for the land, but history is full of horrid things so there’s no use dwelling on something you can’t change.
I personally think you could very easily divide the main series fallout titles (and 76 because IDK if it’s main series or just a spin-off or what) into the west vs east coast games. Not gonna say one is objectively better than the other, but I personally like the story of the west coast games better.
