I can't cite specific sources or anything, but I've been left with the impression over the years that (a) SJG would really like to do a video game of some kind, (b) they've had a rather bad experience trying to get one going (Fallout, and the aforementioned MMO stuff), and (c) they're kind picky about licensing that sort of thing. Doesn't mean it can't happen, though, especially if you pitched them a "finished" product.
