try Navyfield, its a Naval Battle WW2 game. Build up your ship, customize it, gain exp and $$$ for bigger and better guns / crewmen, stats, get bigger ships, choose a country tech tree, etc.
I used to play it but I stopped because "manual cotnrol" is way too much of a pain in the ass, and if you go auto when you get into carriers, cruisers, battleships, etc you lose horribly
