RPGs really haven't been around long enough to have the kind of impact you're looking for, but you will see plenty of sci fi that does this. A lot of Clarke's stuff (notably the communications satellite), Heinlein (battle dress), Asimov (psychohistory)... these were proposed in the 30's-60's, back when people were fond of space and had dreams.
That's why all the cool stuff, like nuclear engines, were developed a long time ago, and nothing of its ilk has been seen in the last 30-40 years. Very disturbing lack of vision.
RPGs so far have not invented anything that isn't already popular in sci fi books, and considering the sheer volume of sci fi books, really, it would be hard to invent something for a game before it could appear as a story. RPGs are set in other people's worlds, near as I can tell. Even Traveller draws all of its elements from the sci fi that was popular in the day, and what came before it.
Maybe in the next 100 years, some one will beat the odds and publish a game with an idea before some one publishes a story about the same subject.
