Well, I would only expect the occasional new game to be made.  I would think that it would be far more common for someone to import a GameDev model into an existing game as their personal custom avatar or whatnot.

     My own plans are to use GameDev output as resource-efficient background/filler characters in massive Poser scenes, both stills and animations.
