Well,i suppose its apropriate to post this here.
I have been working on a Japan faction mod for a little while now,and recently "completed" it,as in,its in a state that feels to me ready to fully play.
I have made the Japanese faction an underdog faction.Their late game is awful.They dont have heavy tanks,and their only medium is doctrinal.Instead,they focus on infantry and light vehicles.
