FTL, Rimworld, MMORPGs (the grindier the better), grand strategy games (Victoria 2, Europa Universals 4, Stellaris, etc), Stardew Valley, Animal Crossing, Valheim, Binding of Isaac, Risk of Rain, Super Auto Pets, and Mount and Blade off the top of my head. Also sports management games.

A personal pick and perhaps controversial is that I like to play Souls games with a podcast on, specifically on reruns or NG+

Edit: Also nobody has mentioned the Civ games yet, they deserve a shout

Tetris

• Dave the Diver
• Most “bullet heaven” games (Vampire Survivors, Rogue Genesia, etc.)
• Returnal (once your lizard brain can take over playing completely)

I spent a lot of time in 2020 listening to Cum Town while playing Cities Skylines.

vampire survivors / halls of torment / death must die

The games take very little brainpower once you’re in game so I find them to be great for multitasking.
