Well, I'm not sure about a stand alone version (VGA Planets?), but I currently run a server for a game similar to Trade Wars, called Black Nova Traders. There's not much activity on it these days, but feel free to use it if you want. Link below.

BTN is the closest your going to get for a non BBS door game like the one I run on RoF.
