Tom Clancy's straight-laced military stories have been fertile ground for video games since 1987, when Argus Press Software (who?) released The Hunt For Red October on ZX Spectrum. However, the series' popularity didn't truly escalate until the original Ghost Recon appeared on PC in 2001, capturing the tense military thrills of the books and marrying them with hardcore tactical shooting. Since then, our Tom has gone from strength to strength in video game form, spawning several established franchises (and a few one-offs) that encompass first-person shooters, flight sims, strategy, stealth and even turn-based battles. The latest - Tom Clancy's The Division - is an MMO shooter, and looks all set to carry the Clancy name into the future. But before that, let's look at the whole series history and pick out the ten best Clancy games of all time.
