SFC4 is kinda like Camalot, young apprentice. It is the game that all the SFB (Star Fleet Battles) fans want to see because it would include the Tholians (living, breathing rocks), the overthrown rulers of a distant galaxy; the Jindarians, their insect-like adversaries; and the Andromedians (from guess which galaxy).
Like Camalot, this is a mythical thing representing an unatainable goal. Mostly it's just wanted for the extra goodies!
