Matrix Game: Guns Of August

[Chipmunk]

So is this game worth getting? I was thinking of picking it up myself as I am a bit of a WWI fanboy. I'm mainly interested though in something that will on the whole be true to the general course of the war and not vary wildly from it. Has it got scenarios that start the game at other times than August 1914, such as Verdun, Somme, Brusilov's offensive, Kaiser's Battle etc?
