I'm glad you liked the chapter titles. They were my idea and were a lot of extra work for Mortze, so it's great to hear that people appreciated them.
I used to work with a woman from Brazil named Thais. Although none of the characterization for Thais came from this woman, that was where I came up with her name. And, in my head, the Thais in the games was from Brazil for that reason.
I've intentionally not set either of the main universes in a particular country. I'd like for people to have the ability to think it's in whatever country they'd like. I do minimal country obfuscation in the games, like having people call "emergency" instead of "911" but I'm sure I'm not perfect at that. For instance, I'll bet I've referred to money as "dollars" at some point.
That said, I live in the United States and Mortze lives in Europe. So, if it seems like the writing feels American but the visuals feel European, that's probably why.
In my mind, the games are set in an alternate world that's very similar to ours, but isn't actually ours. I don't think there's a major city called "Sangrive" anywhere, and Won from Darkness Falls is from a little country on the border of China that doesn't exist. In my next game, Chasing Beth, a war that didn't happen will play an important role, etc.
