I think it's cos it's a map name, like how Thunder Mountain is called "thundermountain" in the game files. koth_el_dorado just looks kinda weird imo. The thread title could have the space but that's nitpicking of the highest order.Why does everyone think that it's "eldorado"? It's "El Dorado", i.e. "the golden". It's like naming a movie "thehappening" or "theavengers".
I've seen a bunch of maps with multiple underscores in them and they've worked perfectly fine. It just looks ugly imoI was told once that having more than two underscores can cause problems. But people say a lot of things.
