I have this game on the Wii virtual console. I also used to have it on my PC. For me it was THE real-time strategy game. Two generals building up their islands, probing enemy weaknesses with recon missiles, then sending in strike forces after softening up enemy defenses with attack missiles. And during the campaign the enemy broadcasts his boasts, frustrations, and finally pleas of mercy to you. The PC version was even more realtime too with missiles and enemy mech carriers flying from one window to the other and when playing against another player you can broadcast to each other. I wish an updated version could come out, or maybe someone else can make a game similar to it.
