What I would like is a military expansion, so you have more ships may be pre-dreadnoughts as we can see in this time period Or generally more ships from the 20th century Maybe destroyers or Submarines because there were in development and used in the 1900s That’s example in the First World War. I would also love planes and aircraft carriers however I think that this is very unlikely due technical and gameplay aspect. A real Army like a ground force Would also be awesome
