Kruggsmash. He's mostly (maybe entirely?) A Dwarf Fortress creator. I first found him just looking for basic tutorials of how to play the game, but soon started watching his series where he uses the game as a platform for storytelling. He takes the procedurally generated stuff and fleshes it out. He voiced characters and made incredibly charming drawings for important scenes.

Camelworks. Rest in peace- the channel is dead because he passed away earlier this year. Mostly did content dicing into Elder Scrolls games, occasionally Fallout and other games.

Is It a Good Idea to Microwave This? - classic old school YouTube, from the days when it waa just high school and college students fucking around. Just 3 dudes with a camera, an extra microwave, and someone's parents cool enough to let them do dumb stuff. They eventually stopped as life caused the 3 of them to grow apart.
