I'm playing Victory at Sea, a naval real-time strategy game by Evil Twin Artworks and Mongoose Publishing.
Featuring three campaigns set around the world during World War II and six historical battles, Victory at Sea also has custom battles where you can choose the ships in your fleet (destroyers, corvettes, submarines, cruisers, battleships, carriers, and torpedo boats). Ships can either be given generic move and attack orders or controlled directly; weapons have specific ranges and orientations that must be accounted for. Aiming is very imprecise and the AI doesn’t adhere to naval tactics and simply rushes towards the opposition. There is location-specific damage, but not until a ship is almost destroyed. The shortcomings with the AI and aiming mechanics make Victory at Sea hard to recommend.
