As of now you can sign up to be on the closed beta for Paradox’s Crusader Kings II. Do you want to do that? I can’t help you answer the question. But if you do, make your way over here, and put in all your most private details such that the publisher can clone your identity and sell you to Russia. This one’s by the people behind Europa Universalis, Hearts of Iron and Victoria, and we’ve written tons about it. So go research, then perhaps sign up for the map-based combat. The full game should be out early next year.
