Senrakyu!! Rengou Kantai/戦略!!連合艦隊 (Sharp X1, 1984, Bandai)
This is Senrakyu!! Rengou Kantai/戦略!!連合艦隊 for Sharp X1 and it is a game where you are playing in a simulation war game that I can't describe but unfortunately it is controlled by two players meaning that I would need another person, but I can usually just attack the enemy that does nothing, but it takes 12 minutes to finish this game and if the last one stands then it's game over. It's an ok war game to play as it's an SWG.
The Ports it was on:
RX-78 Gundam Computer
