Paradox Interactive have released a PC demo of their upcoming strategy game, Supreme Ruler: Cold War:

Building on Supreme Ruler 2010 and 2020, BattleGoat Studios invites you to relive the tension and uncertainty of the Cold War. As the 1950’s approach, the Korean War looms, the Arms Race intensifies, the Berlin Crisis leads to the formation of NATO, and the world anticipates a new World War.

As leader of the United States or the Soviet Union, you must make the correct Economic, Diplomatic, Domestic and Military decisions to successfully navigate your country through this dangerous historical era and increase your nation’s Sphere of Influence on the world stage.

Download the demo now locally from AusGamers.

Our game page has some more information and screenshots. I checked this game out at GDC this year; it looked like one of those pretty cool really hardcore strategy titles with a lot of depth.
