WW1 did have some mobility to its battles. The beginning and ending months of WW1 was pretty much mobile warfare, the battle of Verdun, that started 100 years ago, was also very mobile on its early days.

Not defending DICE, I'm just a avid WW1 grognard. Look to the game Verdun to see WW1 well made and compelling. I don't believe DICE could do WW1 any justice. As it was said, it was perhaps the most depressing and stupid war of modern times, perhaps of the whole history of mankind.

Those who wish to know more about WW1, I recommend the excellent book A World Undone or the excellent channel The Great War, which tells the weekly news of the war as it happened 100 years ago.

In the end, WW1 molded the world to what it is today more than any event in modern time. WW2 wouldn't have happened without WW1, in fact many historians postulate WW2 is the continuation of WW1, with a pause in the 1920s and 30s. And it could have been so easily prevented that it breaks the heart of anyone that reads the history of the events that unfolded during July 1914.
