I know World War I. And there's a lot you can actually do to make the game interesting

Typically we associate WWI with Trenches on the Western Front. Yes, boring grueling stuff. But some interesting things did happen there. But importantly was how different the war was on the Eastern Front. There was hardly any trench warfare there. It was open battle between the Germans and the Russians. Meanwhile in the Alps, a whole new kind of war was being fought between the Italians and the Austrians. Just take a look at the Arditi: http://en.wikipedia.org/wiki/Arditi

Other than that, you can always make a Dieselpunky enviroment akin to Origins. Less bolt action more SMG. Alternate bigger WWI. It isn't impossible to make a good WWI era FPS
