It really is fundamental to understanding why people like Columbus and de Gama were the way they were from knowing the state of Europe at the time. They were violent and desparate mercenaries from a violent and desparate place, when they arrived anywhere their first thoughts were "ok, what can I immediately loot and sell here, if I don't come back with something good my debtors are gonna cut my balls off"

I think having another person on helps keep Matt in the sweetspot of rants that connect actually existing historical lines. On his vlogs he can roll off on a crazy tangent at times; this was better.
