People may have talked about it on older posts, but as a brazillian, I want to say that's funny to see this alternate version of our country where not only it there a good college here, but that college is also great in quantum physics.
It made me search, and sadly I couldn't even find a single college with a major in quantum physics here, either private or public. The closer you would get is a major in physics in USP (University of São Paulo), the most renowed college here. I found a college on quantum only at doctorate level.
Also our empadas are crumbly butterly pies, more similar to french quiche than empanadas, the later are more associated as an argentinian dish here, and we have a bitterly rivalry with ou argentinian brothers (mainly because of soccer, but also economics/politics). And tacos are only found on mexican restaurants here. Maybe RJ could swap to pastel? It is similar to empanadas, but with a thinner and crispier dough, commonly filled with cheese of minced meat, but each place has its own regional variants.
Anyways, I'm enjoying the game a lot, great use of sandbox, nice soundtrack, great characters! Hoping for a harem/polycule/poliamory ending.
