I’m running an interesting game right now. I joined the war from day 1 as the US with the Allies, and right now I’m in August '41. Since February, my landing force of about 250,000 men has held the thin peninsula of Denmark, whilst the lazy AI did nothing. Seriously, UK hasn’t done a thing except sit on their isles and do nothing, but my landing force has held. On one occasion, 167,000 US troops held off about 1,175,000 German, Austrian (Germany didn’t do the Anschluss, and Austria consequently joined the Axis), Italian, and Hungarian troops, inflicting twice as many casaulties as taken.
I’m literally soloing the axis powers, as the Soviet Union didn’t even enter the war yet, as Germany didn’t trigger Barbarossa. They didn’t even do the MR-Pact, they just annexed Poland on their own.
