Game: Serf Wars

Meteor Games' Serf Wars "updated" recently. For most games, an update means adding in a new game system or adding more items to a game's cash shop. For Serf Wars, the "update" makes the game so radically different that previous players will be asked to start building their kingdoms over from scratch. While Serf Wars is still basically a simplified medieval castle-building sim, the game's update expands the role of combat in the game dramatically. Overall game balance has also gotten tweaked for the better. You can now build a more interesting kingdom more quickly, with missions to guide your efforts.
