I went to Steam today and don't see a download for the demo which I thought was available June 10th. Also from your features list it doesn't appear that the demo has a multiplayer option. Multiplayer is a make or break feature for me and my friends. We have been playing Combat Mission for 20 years which uses the WEGO system.
