Having not played it since it was in beta, I gotta say that it's a load of fun. "Numbery" but not so much so as EVE, pretty fast paced, and the mission structure is pretty rewarding and fun.
The graphics are primordial to say the least, but they put up a good enough atmosphere with neat little details floating around.

BTW I do have the newest expansion, Lost Eden. It's ok, but I haven't done any LE related missions.
