I have a handful of "low focus" games for podcasts, audiobooks, youtube video essays, etc.

Vampire Survivors, or almost any "bullet heaven" type game works well. Old School Runescape also has a ton of ways to skill grind with minimal attention needed. Turn based RPGs with minimal story are great too.

Played through a handful of Pokemon randomizers and romhacks while binging King of the Hill.

But the king for me for a while was Elite: Dangerous. Hop in my cargo ship, use spansh road to riches to generate a trading route, and binge stuff while flying fron planet to planet in supercruise.
