[quote name='sp8001']^ Exactly. I think once you start having to license a celebrity likeness and voice it starts to get more expensive and more complicated. Hopefully they can work something out with the great licensed machines... TZ, T2, TAF, IJ, Dracula and The Shadow.[/QUOTE]
Music and sound effects are also a big problem. I mean, the last Star Trek game on the consoles didn't even have the main Star Trek theme, presumably because they didn't want to pay royalties on it! I can only imagine dealing with Paramount on that, or with CBS on Twilight Zone, etc.
Years back, when Creature from the Black Lagoon showed up as a "Williams Pinball" Windows CD-ROM, whoever developed that game took out all the music too and replaced it with generic tracks. I hope Farsight did all the licensing for their upcoming version but it'll be interesting to see. Beyond the music (can't remember but I think there were some '50s tunes used in it) there's not much to license with Creature other than the character since the game itself plays out in a drive-in (I always enjoyed the setting -- it's like playing a pinball version of Happy Days lol).
But, ultimately, licensing a property like that or Ripley's is one thing but having to license the voice, likeness of an actor, the music, sound samples, etc. of a certain "ip" is a whole other issue. The more contemporary it is, the more difficult it would be I'd imagine too.
