This game comes out in a couple hours, and it looks awesome:

It's an open-ended sandbox world where you start out with one ship and then sail around like in Pirates, taking out enemy ships, subs and convoys. You get money and XP, and can upgrade and add ships to your fleet. Eventually you can take over enemy ports.
It looks like the Mount and Blade of WWII naval combat.
