I think there might be one kind of in development but not as a huge priority, since it requires adding new mechanics to the TripleA engine.
I made a representation of it for myself with what mechanics worked, but a) it required some bit of editing for the stuff that didn’t and b) I lost the most recent version that was a significant upgrade in terms of editing-intensiveness. And I haven’t been motivated to remake it to that point. I might be wrong, but contested territories not producing and single round combat might have been some of those features.
