Errant Signal does meta analysis on all types of games but focuses on obscure indie titles. He’s probably love/hate but I really enjoy his style and I love the obscure games.

Icaruslives does all doom mods. Easy 5-10 min vids on all the thousands of doom mods out there.

Game Maker’s Toolkit is all about analysis of game components with the MO of thinking about how to make a good game. Very interesting and well produced

Upisnotjump does a ton of shit but if you’re into the long form style he’s got a lot. Humor forward with quick cut editing so can be a lot but I’ve liked a lot of his stuff
