What's your favorite part of idle games?

I’m making some good progress on my next game, and wanted to ask all of you which parts/aspects of idle games you like the most!
You can tell me your favorite games and mechanics, I’ve also attached a poll concerning playtime.
All of this will be taken into consideration for decisions I make for my next game! 👀

You can reply to this email (if you’re on the mailing list) or let me know on discord!
