Music and sound are crucial. I have set up a little wargame office in my home. I can throw in A Thin Red Line, Enemy at the Gates, a lot of music really depending on the front and what not. But where I think I've gone over the top is I have an extra DVD player, so when I want better sounds I can throw in Patton, Stalingrad, Saving Private Ryan or any war film I have and listen via headphones to add to the noise of war. For this game any John Williams I think shall work, Lord of the Rings and any war movie soundtrack. So the ability to create a multimedia realm when playing a game is key.
Heck, this game might really stretch my multimedia ideas to the limit. Just think, switching DVDs out depening on what front I'll be dealing with. And when Der Untergang comes out and I start losing as the Germans I can throw that in.
Thanks,
