Podcast games are generally games that you are very good at, but also require input at only one level. That's why being very good at the game helps a game become a podcast game, you can turn off your brain to the plot or thinking parts of the game and just vibe on instincts.

So rogue like games often become podcast games for me. But only after I've mastered the loop and the plot isn't happening.

For me diablo games and it's clones. Slay the spire, enter the gungeon, monster hunter. Vampire survivor type games can be good but sometimes you get focused on completing objectives which can mean I lose focus on the podcast for the game. The second playthru of a dark souls type game are usually good podcast games too. Or anything where you're grinding for a bit to earn levels.
