And dont they complain about WWII?

It can simulate both WWI and WWII it requirea changes in bonuses, speed, doctrines etc.
Only thing is how to simulate Great Crisis - Maybe events?
Another thing is growth of industry and resources output during interwar period and how to make it interesting...
War in Russia, crisis, politics, local conflicts... It requires a lot more weight on eco-political simulation to make that worth the effort. But I would like to see such game (even if not historical but only plausible on such long period)
If someone wouldnt like it then could always play mini-games like 1914-192x + 1933-195x + 1945-19xx
