You can download the demo of Defcon, for Mac, Linux or Windows, and play a limited version of the game for free. You should do that now. What you'll get is a deep strategy experience coupled with a harrowing example of the artistic power of games: the gameplay is itself a poetic expression of the horrors mankind might be capable of, and the personal moral implications involved. You score a point for every million people you kill -- I think that sums it up.
