Territory Borders like Total War or Similar strategy games

I’m yet to work on the code.

Two options:

  1. I am thinking Hand drawn Territory borders placed around Hand Placed Cities on the map would look more natural. And can be customised to my needs.
    The more I talk about this, the more I believe the below tutorial is what makes sense.
    Modifying the tutorial to suit border highlighting rather than the entire territory.
  1. Write logic to create Territory borders based around a Territory Range Parameter and Movement Cost Modifiers, I should be able to use grids and calculate around it with the city as the centre, for the First City. All the grid points that fall within the Range and Movement Cost calc, would then be used to find the borders, where spline points would then be populated.
    Then, all subsequent cities will calculate territory border the same way until it hits a grid which is already part of another territory.

I’m marking the question as answered. I have to think deep about which option I am going with for the game.

Thanks for entertaining the question.
