Even though The Greatest Generation is also gone, I bet at least some people here could talk about that game, which I bet would be right up your alley.
Oh, TGG. The wiki's still up. Many fond memories (I was Strife there, along with several character bits).

And it might indeed be interesting for you, since the combat was intentionally a MUSH/MUD hybrid (real-time, but the 'mooks' were run by a GM and if you didn't kind of try to pose Death would yell at you). Outside combat, RP was free-form. One of my favorite online RP experiences, though probably not one that could be replicated. There's been a diversity of things done with the MUSH format, even if individual players themselves might have only played WoD or whatever (I've never played a WoD game in my 15 years playing these dumb games).
