My nuttiest game was a “kill the USA first” strategy in Alpha+3. When you have Germany invading Brazil and Italy taking Panama, Mexico, and the West Indies it gets wierd. All we needed was for Japan to take Honolulu and we win… something he refused to do, throwing the German submarine fleet under the bus.
The idea was that if the USA was so focused defending Hawaii, he couldn’t afford to spend in the Atlantic, therefore 18 german subs there could convoy disrupt 35 bucks from them. Would’ve been beautiful if it had worked. My subs got pasted with the Italian navy as well. I was on the defensive from the Soviets, and Japan ended up taking Hawaii anyways!
