All things considered, this is the most impressive WWI strategic computer war game out there. The way that EAW does not limit a player into the major and well known military strategies and events of the real war is what I like to point out as one of the biggest assets of the game. The approachable amount of moving pieces comes as a close second.
In real life, as explained in Buchanan's book, the resilience of the forces at the turn of the 20th century brought a self-sustained colossal catastrophe that ultimately didn't end all wars. The challenge of the player in EAW is to make just enough good strategic decisions to end at least this one.
