Did you ever see that thingy (think it involved editing a bit of a file in the Hellfire expansion) to include the "Cow Quest" in Diablo 1, with the guy dressed in the cow suit? I loved that.
"Moo." "I said Moo." "I'm a cow, ok?"

Oh, and, yes, I'd really love a new Diablo game. Hopefully one of these days (or years).
