what are some great YouTube channels worth checking out?

Not many I follow too closely to be honest these days. I just did a big purge of a bunch of my subscriptions so there's only a handful now.

Gaming/Entertainment:

• Nextlander: General gaming; comprised of three ex-members of Giant Bomb (Vinny, Alex, and Brad).
• Mr. Samuel Streamer: Primarily focused on Rimworld and Crusader Kings, just an extremely witty guy that puts a lot of work into what he does. Often spends 8-9 hours in gameplay and editing to make a 30 minute episode, every day.
• Nilaus: Factory/automation games, like Factorio and Dyson Sphere Program.
• The Jimmy Dore Show: Semi-leftist, has liberal tendancies but is more political comedy than serious commentary, so I categorize him more as entertainment than political. I often don't agree with all of his takes, but the show can be good sometimes.
• CryptTV: Mini-horror episodes, often with a few recurring monsters. Really well done effects work.

Politics:

• Li Jingjing: China-based journalist, covers China and the global south as a whole. Does both serious stories and cultural/interest pieces. Great for somebody just interested in seeing more China without the anti-China rhetoric.
• George Galloway: Left-leaning talk show host, some reactionary tendancies but he does have a pretty good range of guests from time to time, including the above. He's been around for ages, very well established.
• The Deprogram: Leftist talk show and podcast.

That's kind of my entire subscription list at the moment, it has been cut down a lot recenty.
