Disturbing...
I am amazed that such choices can result in such an apocalypse as the "Mutually Assured Destruction" of the whole planet. While the gameplay was somewhat impressive, I found it awfully repetitive most of the time (The news-flashes were interesting and semi-humorous). The storyline was what really got me hanging. Ultimately exquisite to the highest point of realism. Good job, sir. you've scared me for life. (Yes, scared!)
