Cow Clicker and Cookie Clicker are not idle games. You have to interact with them constantly and the less you do the slower you progress.
Idlerpg for IRC is the opposite. If you act you are punished.
Progress Quest is totally idle. It has a bunch of internals that just increment numbers and pretend things happen. It’s an app you start and then don’t do anything at all with.
All the clicker games, and the weird unfolding games like A Dark Room, Candy Box, Paperclips, are kinda fun but not in the spirit of Progress Quest.
