I think these BC games would be fun if the interface were a little better. Right now it's kind of non-intuitive, and the menu system doesn't really fit the simulation (what I mean is, were you really in a battlecruiser, I'd think you would control it by buttons and levers, or maybe some kind of Star Trek like GUI, and probably not by the hierarchical menu system).
I bought the game when it first came out (i.e., when the unplayable alpha build was released in stores), and later bought the completed version. Because of the non intuitive interface, though, I haven't really been able to get into it.
