why not some cold war scenario? who cares about real life, thats what game is for. Make the US and USSR duke it out during some imaginary 50s conflict, when subs were not so much better then in WW2, but you can have some nuclear too.
on other hand, why not not finally improve gameplay in terms of wolfpacks.add real shadows. Allow play for Russian and Japanese and Italian and French and UK sides.
And while it will render the tag Silent Hunter pointless, Id really like to have some Violent Hunter too where I can command Battleships and stuff. Violent Hunter is copyrighted (just in case
)!!
