Precipice
Take control of the United States or Soviet Union and provide technical and economic assistance to guerrillas all over the world fighting for your cause, all while avoiding a direct and open-confrontation with the enemy.
In Precipice, subterfuge is the most important strategy. Safeguard your closest allies and change unfavorable regimes without giving away your long-term ambitions. Every action risks an enemy reprisal, and if nobody backs down from a standoff, we all lose.
