Ooh, from the way you phrased that it sounds like you may not have ever encountered Colville before? If so, I'll just say I cannot recommend his stuff highly enough. He has an enormous series "running the game", most of which is aimed at GMs but much of which is also useful for players to have an understanding of. He also has a few videos on the history of the game/his experience of the game from way back in the day, as well as some of the history of other games. He's done a bunch of media criticism and analysis, including a mini-series on 2001: A Space Odyssey as well as ones about bigger nerd-culture franchises like Lord of the Rings and Star Wars. Videos about online or societal discourse, including both related to RPGs and more broadly applicable in society.

He's also the CEO of a company that used to make 3rd-party D&D 5th edition content but is currently developing their own RPG.

I've obviously only linked a single example of a handful of different subjects, but I highly recommend going through his upload history and seeing what strikes your fancy. I often find myself disagreeing with his takes in many areas, but have never once failed to understand where he's coming from and believe what he's saying is at least worth discussing.
