Thanks for the feedback! Yes, the elements have a bigger role than just gathering the main resource. Each territory is influenced by the territories around it, affecting both the amount of resources produced and the production speed.
One idea I didn’t have time to implement was generating the map randomly, so that each game would have a different combination of territories and the player would have to decide which ones were worth conquering based on how they influence each other.
I agree that multiple character selection would also be a great improvement. Thanks again!
