I don't think you can call Tom Clancy's universe sci-fi.
With the release of H.A.W.X., I beg to differ. Tom Clancy's H.A.W.X. is by far science fiction.
Not really, though I can see why some folks might think so. It's best to stick to the more "classic" examples of sci-fi. Besides, the example you cite is a game as opposed to film, TV or book - the raisons d'etre for this forum.
