That sounds pretty cool hactually, but then, I like all these unexpected endings and stuff. As a bit of an elaboration, for the final cutscene, I would have the camera panning around the players ship/convoy in subspace, hearing snippets of speeches from the Knossos project fading in and out "We've all worked hard for this day" , "The TV Knossos project is undoubtedly the greatest and most outstanding of all joint Terran Vasudan projects, for, unlike the Collosus of the past, we are now united not in a work of war, but in the quest for knowledge, in short, we unite in the spirit of peaceful coexistence between our two races.", "Today, we celebrate the first true defeat of the destroyers since the great war, but tomorrow is the true victory, when the greatest wound they have left on our space is finally healed", "Good Luck pilots, and Godspeed" Etc. Etc. Then the player gets all happy and proud of himself, until he sees the blackened husk of earth, completely changing the tone of the cutscene. Big musical buildup, bring up see earth, cut music, 2 seconds later, cut to credits.
