A challenge for "The Great European War", a war raging from 1912 to 1919, with a variety of vehicles seeing combat, but before you go make random crap, there are some rules you must follow
This war lasted 2922 days, or exactly 8 Years. This will be important during the rules list but don't forget this is 10 months long so I don't have to post as many challenges. But it will be important by each year so here is a calendar:
1st Month: 1911
2nd Month: 1912
3rd Month: 1913
4th Month: 1914
5th Month: 1915
6th Month: 1916
7th Month: 1917
8th Month: 1918
9th Month: 1919
10th Month:1920

Rule #1: only start by building Balloons, warships (except aircraft carriers, must be accurate so Pre-Dreadnoughts, Dreadnoughts, Super-Dreadnoughts, Destroyers, Armored Cruisers, Light Cruisers, Heavy Cruisers, Gunships, Submarines, Gunships, Gunboats, ect.), and armored cars
Rule #2: No tanks until the following dates: UK, France, and Germany: 1914. Poland, Russia, Austria-Hungary, Italy, Spain, Ottoman Empire, USA, and Mexico: 1915. Brazil, Argentina, and Japan: 1916. Everyone else: 1917 or 1918.
