Divisions are made up of thousands of soldiers in the game, and I am not advocating either that it worked in turn based so it would be perfect here. I've argued this with some other person who cried it could never be modeled in this game.
Not HoI3 but HoI4, and yes it can be implemented easily. We have thousands of ships in the game, and millions of soldiers each tracked individually. Soo . . adding another layer of tanks and airplanes would sink the game? I seriously doubt it. For HoI3 most likely, but not an optimized HoI4.
Just because this game has had and still has problems, any new additions will just kill it? Come on where is your vision Slan? Anyhow, I am not even referring to HoI3 so please refrain from referring to this addition only to that game, and instead think ahead to the future. Each new Paradox game comes with additions making it slightly more complex. I think in HoI4 there should be this third layer added into the game, and then and only then could we (AI, and game working smoothly) have a very good representation of the war.
Well, I have vision, but I tend to get bogged down on the ground, unfortunately... What do you mean by 'another layer'? It seems that I missed something...
