TBH, Extra Credits was actually pretty good early on when it was part of Penny Arcade, especially when they focused on the nuts and bolts of game dev concepts. However, the last few years, the show really went down hill. There was a #MeToo moment with the writer behind it, James Portnow, that seemed to have caused several of the major people involved to leave the team, and since then the channel double-downed on SJW political stuff. They do a bunch of side stuff like analyzing historical events, but even those are probably heavily tainted with leftist lies these days. I had a hard time stomaching the content any more after Daniel Floyd left.
