I believe this scenario you are describing is actually one in which Stardock has no interest in compromise and gets about everything it has asked for. An actual compromise might also include Stardock giving P&F the right to call their game Star Control: Ghosts of the Precursors plus an agreement that sees all rights ceded to P&F after a reasonable number of years, for example.
Stardock getting everything it wants does not need to be a terrible thing. They initially tried to license the rights to the original aliens.
If the agreement that is forged maintains the Alien names and distinctive natures as property of Paul and Fred and the Star Control TM property of Stardock, a cross licensing agreement where Paul and Fred are paid by SD for the right to use the Names/races could actually fund Paul and Fred's Game.
Paul and Fred then publish using the Star Control: Ghosts of the Precurser's name and pay SD for the right to use the Trademark, or have Stardock be the publisher and not even need to worry about paying for the TM. In the end the fans would get two games. Paul and Fred would get to keep their story, and StarDock would get get something out of spending 5 years reviving was was basically a "dead and forgotten my most" game series.
One side does not need to lose. All sides can still win.
I'd rather have three winners.
