I watched his first video a while back, and it appears to have revived some Asian(edit: Korean ) MMO(surprisingly, one I never heard of.)
When he was going over features that are relevant in the game again, he gets to a point where he discusses colleges. A completely player-ran event that has special tools from the game to be able to give lessons.

MUDs & early MMOs used to have a lot of cool, weird systems you wouldn't see today. Arguably we're past the era of WoW clones into … nothing …
But it's strange that tabletop RPGs are supposedly so popular, yet we rarely see things that might actually happen at a tabletop put into video game RPGs. Is it the critical role effect where most people aren't actually playing RPGs but having amateur group acting lessons?
Wanted to share this thought that popped into my head before I forgot.
