Ancient games: The game of Uuuuuuuuuuuuuuuuuuuuuuuuurrm?

Bad post titles aside of all the ancient games that I played the ancient game of Ur was my favorite. It was simple enough to understand the rules and be able to make some very cunning plays. This is the game that I have decided to iterate on and make my won game out of and I think the changed that I have added to the game will make it a bit harder to grasp at first but will open up more chances for tactical moves for the the two players.
