Supremacy was a board game from the late 80's that was like Risk on steroids. You had to balance your military, your resources, and economic and technological development. You can have nukes and laser satellites. Corner the market for billions in a cartel with other players. You can sell nuclear, chemical, or biological weapons to neutral warlord nations or pirate fleets. We used to play tons of this game.
