Hi! Thanks for the kind words :)
I am currently adding to Emperor mode. Right now I've added a diplomacy screen where you can directly propose peace / alliances etc, rather than relying on spies. I also added a shortcut where you can advance a certain number of steps and then pause again, kind of a semi turn-based approach to the game. I also want to add a way to focus resources (think Generals) to specific fronts, to help you prioritize where to wage the ground war.
Nice videos :) You need a more powerful machine though! :D
