Please go watch OneShortEye. I already love speedrunning and glitches, but seeing how the unique artistic angle of early adventure games leads to surprising quirks and bugs is a special kind of charming. His video on Robin Hood and the complexity of the point system judging you for your actions, leading to the fastest way to beat the game being to be the worst Robin Hood history has ever known, is a standout.

I would also highly recommend Dungeon Chill! He covers a wider spread of games than just old-school point and click adventures, but his long-form reviews of story-based horror games (especially ones limited to Japanese releases) are wonderful looks into the medium. And he has great appreciation for the weird and wacky oddities that come out of early artistic experimentation in games.

The Creator once met Ken and Roberta Williams and Dave Gilbert at a game faire and watched them play a game the Creator had worked on the art for (NOT one of their games, they are just on art). Idk had to sneak a little not-so-humble brag in there. Space Quest Historian really is that tall, in fact he's taller.
