Greetings to all!
It wouldn't hurt to make a realistic damage system. For example, if a ~ 305mm caliber hits a destroyer or light cruiser, it should actually be torn apart. And besides, battleships can spend hours firing at each other and not break anything to each other. This is very bad.
It would also not hurt to add the system "designer according to drawings", I.e. to allow you to freely draw the ship hulls, and the game would have already adjusted this drawing to a more or less normal structure. As well as designing guns and towers (add a purely free drawing editor).
Add concrete ships.
Add system of damage control. I.e. distribution management crew to resolve the problem (prioritization).
Add a system that prohibits firing at extreme negative angles. in Other words, you will have to flood another part of the ship (make adjustments to this parameter).
If possible, add details of damage, chips, etc.
Add a normal system for launching torpedoes (sometimes they just don't launch, even if the enemy ship is nearby)
Add splash effects from projectiles that fall into the water
Add the min constructor and min reset systems
Add a 3rd-person camera setup that allows you to follow an object without moving the mouse (it would be very useful when the combat speed is x5 or higher).
And most importantly-do not break players with a game without a campaign mode for$49.99
