@AlexandermbGreat stuff!!!!!  For the Roman Army camp, however I am not sure, but I would believe that they might not have taken the time and effort to implement paved stairs but rather wooden stairs. What do you think?

I like the idea of Mayan glyph being used as icons; many of them are old enough to span the entire period: Ajaw: https://en.wikipedia.org/wiki/Ajaw Balam (Jaguar) Kaan (Snake).

No, it doesn't.  YouTube already has a lot of money, they don't need more. I think what they did with streaming services and SAS in general should be prosecuted, and everyone involved with this world-dide extortion scheme thrown in jail. Not just in YouTube, but in every major streaming giant.
