Hi Berger!
This is a fascinating topic to look into, especially given your unique parental connection with Brazil. I've seen Favela's in photos before, and the construction (at least of what I'm seeing on Google right now, typing this) is really a marvel to look at. Thank you for sharing context into why these buildings are so closely packed. Beyond that, I think framing a setting for a potential game around Favela's would be interesting to explore aesthetically, so if this project does work out, I'd be very excited to see how the architecture translates into a game.
