Doubling the Chip and Ironicus rec. They are best known for the Metal Gear LPs, which are tremendous, but might not be work safe. But check out the Beyond Good and Evil one, def, and I rewatch the Cabella’s Dangerous Hunts LP every year because it’s still hysterical.
It’s weird but I’ve been watching them since the LP subforums on SomethingAwful and seeing the production value increasing with time makes me… weirdly… proud of them. Super mega rec.
Another good one that I love is Cryaotic. His LP of Okami is very long and enjoyable and will kill at least a few days for you.
ETA: Oh for GDQ streams, I use them for background noise a lot too! I would rec looking up the 4 player co-op Majora’s Mask run, it’s 4 hours long and mindbogglingly skilled and extremely entertaining. Also, anything Puwexil does, as he mainly does long games like Chrono Trigger, Final Fantasy, tho my fave is his Illusion of Gaia run. And the marathon-ender Mario and Legend of the Seven Stars I remember being excellent. All great stuff!
