Fixed that for you
To be honest, there isn't a lot to explore in that "genre" but considering I have seen idle games where you are raiding dungeons and when you are not letting it go idle choice does matter rather then clicking "matters" (though, especially in the beginning clicking as often as possible is also a good thing) I would say that everything that has only stuff like
click to get some number up
buy upgrades for click
buy something that generates said number over time
buy upgrades for said stuff
as a clone of cookieclicker. Reason: it doesn't add something new to the table and everything it does is also done by cookieclicker and the thousand of other idlegames.
