Arguably, almost any Idle game is a Groundhog Day simulator. You end up doing almost exactly the same thing again and again, but improve over time as you gain in experience and understanding...
Just curious, this is one of my most downvoted comments and seems pretty innocuous, would love to know why it seems so objectionable? What am I missing?
Not sure. Perhaps misinterpretation of what you mean by Idle game (usually people mean that genre of silly Flash games where you don't do anything, just watch) or (less likely) grammar sticklers who see inappropriate use of the horizontal ellipse (i.e., …) as laziness?
