if I could code, I would wanna make a modern sub sim, but it would placed in either the Pacific or atlantic or indian ocean. It would be derived from the game 'Submarine Simulation' because you could actually go pretty much anywhere in that game, which is why it was so awesomeness.
Cept it would be like a freeplay sort of game, where you will like get a mission like 'Sail to the Sea of Japan and spend a 1 week patrol of the area there' or 'Oh Noez red october is going to America!' or something, or you could be a rouge and nuke Russia or something awesome like that
But i dont have coding abilities. Unti lthen, ill have to do with this great game
