For a strategy game the 1 thing I would like to see is the ability to have ship(s) be able to save move and react to enemy ships as they move near by. Basically they would be lying in wait and respond to encroachment. It would interrupt the movement of the current npc moving and force a battle. It would add a huge strategic level to the game and I don’t think it would take that much to implement.
To implement a button would be added to the ship options window. And then code to auto move the ship to intercept when a ship comes within range of the movement radius of the awaiting ship. Exact implementation could vary, e.g. when a ship comes within range does the intercepting ship do full movement or do you go with a 1 to 1 pc moves allowing for pulling ships and fleets away?
The hardest thing to about it is AI. That is where it eats up programming time I would think. But I still love the idea and would love to see it.
