Simcountry is a multiplayer Internet game in which you are the president, commander in chief, and industrial leader. You have to make the tough decisions about cutting or raising taxes, how to allocate the federal budget, what kind of infrastructure you want, etc..
It is not profitable to sell strategic weapons. Normally if a player thinks he/she has enough then he/she stops making them.
