I am going to be super bummed if they don't announce some kind of pirate themed game.
Especially after how amazing Black Flag was but was so held back because of it's ties to the AC franchise and couldn't just be a good full fledged pirate game because of it.
Then they sent out the survey asking if people would like a pirate game without the AC tie in.
So I'm really hoping they did something with that.
Imaigne a black flag style game but where you start out at the low tier with just a small ship and then you have to make your way up the ladder, either through normal means (IE trading goods, military service, etc) or through nefarious means (IE Pirating) to get bigger/better ships.
Then you have to actually find crew members that have their own story elements (like party members in say, Mass Effect) with their own stats that influence your ship and how it behaves in combat and sailing.
All wrapped up in a world with quests/npc's and stories to find.
