A long time ago, back in my days growing up in Winnipeg, I purchased a game called Pax Imperia. It was a 4X game devoted to taking over the galaxy. What was cool about it was the level of detail in ship design. You could tweak the design of weapons, shields, and engines in very specific ways.
One of my proudest achievements in the game was that I could design weapons that were very good at maximum range and utterly useless at short range. I then put it on ships with very good speed. This was a devastating combination. Enemy ships would try to move to a closer range, and I would do my best to keep just the right distance between us. My weapons would rip them to shreds, while their close-combat weapons would never get the chance.
The fact that the empty spaces between stars were not just something you pass through, but a place you could send ships helped with this. I could choose to approach enemy stars in the form of a phalanx of ships. I was unstoppable.
This strategy collapsed when my ships were in an enemy star system and they suddenly built new ships. These ships appeared within the dead spot of my weapons. I couldn’t move away fast enough and my ships were destroyed. It was still a good strategy.
I’m sorry I never finished the game. There were other problems with it such that it didn’t keep my interest. That, and I had school.

Last Christmas, I was exploring the USS Lexington and saw the scale model of the “Dreadnought”. I did research on this ship afterwards. It was a major innovation in battleships, and all ships afterwards were referred to as Dreadnoughts. It brought a lot of new ideas to ship combat. A key point was the “All-big-gun” idea. Previously, battleships would have a range of weapons for varying distances. This was in keeping with the prevailing theory of naval combat that battles would initially be fought at some distance, but the ships would then approach to close range for the final blows, when the shorter-range, faster-firing guns would prove most useful.
The innovation was to just use big guns, which were easier to target and did more damage. Battleships never seemed to get into close combat, so focus on doing what you are good at.
That sounds familiar.
So, I’m a little proud of myself. I had, independently, figured out the same idea that changed modern warfare forever.
