Isn't there some sort of counter that says how many times a map has been played?
Sometimes I think we get so stuck in the usual rut that new maps could come out, without the majority of players not even noticing it.
I do agree though that there should be an audit of broken, outdated maps.
Imo, maps without a "Choice" at the end really need to be nixed. Having a map with just a "CONGRATULATIONS YOU DID IT" as the only ending is kind of lame, I'm not saying all maps without minigames should go, but at least have the common decency to offer a "Instant Win" or "Humiliation" ending.
However, that is personal perogative.
