Yes, yes, yes, I saw this idea on a map that you suggested. Undoubtedly, it’s very interesting, but it’s important to understand that in games where it’s implemented (Civilization, Total War), the player has almost endless opportunities to expand and, consequently, increase their capital. In Heroes, however, the size of the map severely limits your income. You can make a very large map, but then there will be, at the very least, a problem with the AI, and recent experiments show that it’s not just the AI that’s the problem (because the AI problems seem to be solved with a special mod, but new ones aren’t). So, I see it this way: first, the game needs to be adapted to the largest map sizes so that it works without glitches, and then you can create an empire on it that implements everything you want, for better balance and enjoyment of the game, including this feature.
