Custom enhancements to the game Nuclear War

About Nuclear War, from BoardGameGeek:

Nuclear War is a satirical card game in which each player represents a "major world power" and attempts to gain global domination (or annihilation) through the strategic use of propaganda or nuclear weapons. Players start the game in the "peace/cold war" phase, using Secrets and Propaganda cards in their hand to negotiate with other players. Play continues until the first player launches a missile and payload, ie the "war" phase. If the missile isn't destroyed in flight, the struck player must spin to see how much of his population is lost. Play continues until either peace breaks out again or only one player has any population cards left. Limited edition booster cards were created in the 90's. A list can be found in the Community Wiki section and Nuclear War Booster Packs
