Download the demo, experience this incredible feeling.
Very few games evoke such deep feelings, and do it so subtly. It is worth it to feel the sadness for the state of this world. To walk away from the game ill at ease and a little scared. It is subtle, but let it affect you. We do not have to become desensitized to this.
The pace is radically different from most games. The real-time speed is majestic. It takes 20-30 minutes for a nuclear missile to fly over the ocean. Do you think someone would tell you if one was launched? How would you spend your last half hour?
