Battlefront.com features a new playable demo for Strategic Command WWI Breakthrough, the World War I (now WW2 as originally written, apologies) strategy game. Multiplayer modes, saving and unit purchases are disabled in the demo, but it does include these three campaigns: 1914 Call To Arms (limited to August -> November of 1914), 1918 Ludendorff (First 5-6 turns), and 1918 Russian Civil War (limited to Nov 1918 -> August 1919).
