Sierra and Microsoft have revisited the grid-based fortified town of Carcassonne, as the XBLA rendition of the popular European board game has gotten a new downloadable expansion titled "The King and Baron" as part of today's regular XBLA update, which also includes block dropper Tetris Splash.

With an asking price of 300 Microsoft Points ($3.75), the download is the second such expansion following the already available "River I & II," and adds a set of five additional tiles described as 'interesting configurations of Town pieces,' as well as pair of new rules. We're not exactly sure what they mean by "interesting" ... perhaps they glow.

The new rules are designed to award those players with either the largest city or the longest road at the end of the game with a pair of icons placed next to their avatars and Gamertags. But it's not just for looks or bragging rights, no sir! With this expansion, the player with the biggest city, identified by a newly added 'portly' King icon, will receive one point for each completed city in the game, while the player with the mightiest of roads, denoted by a 'crafty' Robber Baron, will take home one point for each completed road in the game -- and you know how much we love to pile up them points.
