I didnt realize this was about Games. but I'm leaving this here anyways

Palestine Focused leftist channels: The Electronic Intifada, Justin Podur, Adnan Husain, Mizrahi Prespective, The East is a Podcast

I listen to Alexander Mercouris for ukraine updates.

Occasionally good geopolitical analysis Dialogue Works, Glen Diesen, Danny Haiphong I avoid interviews with Larry Wilkerson Jacques Baud Ray McGovern Larry C. Johnson Paul Craig Roberts Chas Freeman and especially alex krainer. They all just say the same sort of thing over and over and/or are reactionary idiots.
Jamarl Thomas is hit and miss, He gets more varied guests even if some of them are duds and he is willing to debate and push back against his guests a bit.

Sean foo is pretty good.

Primitive Technology is fucking chill. Just a dude in queesnland australia making shit out of clay and sticks using stone tools. It isn't "survival" content. He doesn't talk or get into clickbait bullshit.

Not really "Games" related, but besides well established Marxist channels like Hakim, Lady Izdhihar, and Yugopnik, as well as news outlets like Breakthrough news, Mintpress, Grayzone, Mondoweiss, etc.. Some of mine but far from all:

Indie Nile is pretty good. A Palestinian drag artist who makes videos talking about Palestine, the Zionist entity and Western double-standards.

This guy is very informative when it comes to the perspective of the former eastern Ukraine which were liberated, particularly Mariupol and countering Western propaganda regarding the proxy war. Not explicitly a leftist but still enjoyable to watch.

DPRK Explained for learning about the DPRK.

Another DPRK channel

A channel uploading old radio broadcasts mostly from West Asia and North Africa, but also others including Cuba The Libyan Jamahiriya uploads are of particular interest, and there are also ones from various SSRs.

Channel archiving and preserving Jamahiriya-era Libyan revolutionary media, very important.

Mostly shorts-content based news channel focusing on the AES Sahel states recommended for those wanting to keep up with the news there. Not perfect but provides a good overview for further reading.

Channel about Mahmoud Darwish poetry

Ambient videos based on historical scenes and atmospheres

Aliensrock for puzzle games, City Planner Plays for city builders, Laith for paradox slop are currently my three highest gaming YouTubers I think.
