I need to dig an idea first

This is the launch of the idea of a war game that discuss the Algerian revolution

So as usual the game is open source and you can access it on my GitHub, but the things is that I have the map of my country in mind and a sort of explosion in a city like Algiers

After that I have some photos in mind from https://manuels-anciens.com or https://bledtube.com from the history courses

After that I am stuck

I really don't know how to start coding this game but it's here

I think we can choose between Algeria and France in a point of view of the player, and ask our self who will win the war or the battles
