The game - Cosmic Wars - Dendy | NES

Space turn-based strategy with elements of the economy. You will not just need to fight on a certain map with enemy units. You need to buy your units, hire a commander, give him a command, put him in position, and then start attacking. Each player at the beginning has 12 planets, which must be protected and conquered new ones. The rather long and boring process of preparing for battle and building up power pays off in subsequent battles.
