I know I've mentioned before that I find it a little sad that World War II gets "almost all the love" when it comes to hobby gaming, since I find World War I all the more interesting. It was the war that pretty much defined the 20th century and introduced a lot of the weapons of war that are still in use today (though obviously heavily modified from their damn-near prototype versions from back then). So with that said... err... typed... I bring you Weird War I for Savage Worlds, which is up on Kickstarter now.
More than just a new setting book, the tome brings you new options and ways to run your games. The Mission System helps the GM create very narrative encounters for your group. From things like air raids and patrols to coastal raids, this system helps keep players involved, even as the GM narrates what goes on. Then, if things get hairy, you can head back to the "normal" system to work out the details. That's not all, of course. There's new equipment, Edges & Hindrances, ceremonial magic, and more.
The campaign is more than 2x funded already with still two weeks left to go on the clock.
