As the game will happen in near future I doubt that naval weaponry will decrease back to WWII level or something, which may probably mean that ships are armed with bigger and bigger anti-ship missiles. Just as a question, if it is possible to control one ship and even micromanage things in it will we just jump to next ship when some evil foe decides to let us taste some 2030 version V2 missile? Or will the ships be able to take several hits?
Other thing, the seas have very little well marked borderlines so how the advancing will be indicated? Or will it be just crazy skirmish until enemy navy is down?
Good luck with the game, I'm so in love with WWII submarine simulations that I can't wait to get myself on surface along some Paradox game
