Europa Universalis II is being offered for free for the next few days.
Europa Universalis II invites you to a global struggle for supremacy from the dark times of Jeanne D'Arc to the flaming wars of Napoleon. As the leader of a country you have to guide domestic and foreign policies. Engage in religious struggles, set up expeditions to claim the New World, lead your country to prosperity and victory. Send your Privateers to roam the seven seas, muster mercenaries to bolster your defences, and send missionaries to convert infidels to your State Religion.
