I'm trying to write up an AH background for my own version of Deadlands Hell On Earth. One idea I had was no American involvement in WWI. I don't know a lot about the period, so I'm really looking for ideas of the impact on the course of the war and the post-war period.
So, no Americans, how does it affect WWI and the aftermath?
