Idle games are fun to run while you do other things, such as more Steam games. Here are the ones kitty's tried.

Games that the algorithm or tags claim is "idle," but gameplay proves they aren't all that idle. Could be anything from "check every few minutes as you multitask" to "better leave window on top."

Games where kitty has managed to do a Steam review. Finally hit the 100-game limit, so trimmed older and less-liked games.
