Irem developed and published many games for the NES / Famicom, such as Holy Diver, Hammerin’ Harry and Deadly Towers. They also had many projects that were never released, and this “Geopolitic Shima ni Okeru Kokka Kobo Ron” is one of them.
This is a really obscure and forgotten strategy / simulation game planned for the Famicom, and only a couple of images were found in a japanese magazine by Youlute.
It seems players would have been able to plan their war against enemy armies, to control the whole world. As it happens with old, cancelled 8 bit games, we don’t know much more about this one: at least we can now remember its existence. Maybe one day someone could find a prototype and share it with the world.
