I have a Steam collection just for that purpose, called "zone-out games":
- Factorio
- Euro Truck Simulator
- Viscera Cleanup Detail
- Satisfactory
- Space Engineers
- Hardspace Shipbreaker
- Rift Breaker
- Monster Train
- Jupiter Hell
- Vampire Survivors
- Dorf Romantik
- DOOM (any)
- Nethack
Some advice I want to give is that "games that require a lot of skill" is only a temporary blocker. If you enjoy a hard game enough to play through it repeatedly, it can become a podcast game. Many people play Bloodborne or Binding of Isaac to audiobooks, and roguelikes are generally like this.
That in mind, I have a list of games that are valid podcast games but I haven't built enough familiarity with them yet:
- FTL
- Binding of Isaac
- Terraria
- Risk of Rain
- Against the Storm
