I assume the person who made the video did more than just read the cited papers, but added some of their own analysis and commentary on top. Like, for any paper that cites sources you cannot get the its meaning merely by reading the cited sources. That’s absurd.
Presumably you thought the video’s content was worthwhile, because you linked it instead of the papers directly (which aren’t even about DND).
Video is a shitty medium for many use cases, but is popular because it is monetized more, and many people are only semi-literate.



There might be meetups near you doing games. There’s one here in NYC that’s very friendly I’ve been to.
