Jacob Geller is one of the best video-essayists on YouTube. The thoughtfulness with which he approaches games as pieces of art is rare, the sleek, striking way he presents his theses is rarer still. There are youtubers that I find more entertaining (HBomberguy, Folding Ideas) but no one that I find more engaging.
"Who’s Afraid of Modern Art: Vandalism, Video Games, and Fascism" in particular had a profound impact on me (also loved the one about Golems). Being able to watch the better version of his videos (without the butchering to avoid YouTube's copyright strikes) is like 80% of the reason why I got a Nebula subscription.
