A playable demo is now available for Europa Universalis III: Heir to the Throne, the strategy game expansion that's due for digital distribution on December 15. The expansion requires ownership of the game as well as the previous two expansions, but the demo is a standalone release. Word is: "Play as one of eight major European powers during the turbulent years between 1492 and 1550. The Age of Discovery would forever change the future of Europe and the world. Vast new territories await discovery, even as the cracks widen in the unassailable unity of the Catholic Church and the Mohammedans march on Vienna. Choose Castille or Portugal and discover the Americas! Expand your trade league with Venice or the Hansa! Experience the rivalry between Bohemia and Austria as they vie for control of the Holy Roman Empire! Conquer Europe with France, or unite the British Isles under the Tudor dynasty! Full gameplay included; the only limit is the time frame, save/reload, multiplayer... and your own imagination!" The 266 MB download is posted on the Europa Universalis III Website and mirrored on AtomicGamer, FileFront, and Worthplaying.
