From Vivendi Universal Games:
You are the leader of your own kingdom and domain, and it is you who have the power to wage war or preserve peace. At a single command, armies march and kingdoms fall. With the abilities of a born king, you command heroes, wizards, and mighty armies. But will it be enough? Many new features have been added to this new demo, including full multiplayer gameplay, the ability to play the full Birthright realm game (includes basic, advanced, and expert modes), the ability to choose from 17 unique and distinct realms and 34 powerful leaders, and final game sound and art.
