The thrilling paranoia in Warren Spector's RPG/FPS/stealth/action/adventure magnum opus has yet to be matched since its release at the beginning of the decade. This genre-bending title is as thought-provoking as it is fun.

Even though it came out pre-9/11, Deux Ex has a skyline without the trade towers; the game's backstory reveals that they were destroyed by terrorists. Let's hope the developers weren't as prescient with the game's pandemic plot line.
