As I recall, it was also common for computer games to be licensed like that, particularly for Trek.
I remember specifically because the Dominion Wars computer game could only use the ships feature in the DS9 shows - it wasn't a big deal since most of the main starships showed up there at least once, but still - if the Akira and the Galaxy had shown up in at least one ep. Simon and Shuster would not have been able to include it in their game.
Its a rather evil way for company to license their IP, especially in the field of comic books.
Its the main reason I have avoid licensed products like the Authority game by Guardians of Order. I want a Wildstorm game, not just an Authority game.
If Viacom started licensing a Enterprise, Next Generation, etc games to different companies then I would pass on the whole thing. I mean, its not like I don't have CODA and ICON to fall back on...
