Hi Steve, thank you for sharing yor monster simulation-game with us, I've been playing it for years now.
I know it is probably last or perhaps second last point in your list, if it does even exist, but would be possible to change the way objects are shown on the map? I've always found this small circle for everything very monotonous (ships, missles, planets, asteroids...).
Let's say, to begin with, to implement a different icon for military and commercial ships and for missles, nothing of complicate, just a different icon to display them instead of rounds.
I am sure many of us here would came up with different solutions that you could then apply.
