World of 3
World War 2
In this version of earth, there live 3 races. Humans, elves, and beastmen.
WW2 progresses much the same, with the holocaust including the extermination of anything not human. Though Japan seems to be more accepting of beastmen.
All the races are pretty much everywhere, with the treatment of other immigrants and colored folk in the USA.
The US still joins after the bombing on Pearl Harbor.
The game starts when the US first joins. After Pearl Harbor.
There is also a bunch sci-fi Dieselpunk. Think steampunk like stuff, but diesel.
So, walking tanks, giant airships like real flying fortresses.
If you want to be a bit more accurate to the events of WW2, then feel free to watch this video.
Otherwise, I'm fine with going a little off script. And if you're a history buff, screw it, we're not doing it perfect on purpose.
