I love it, but I'm always anxious, nervous, and sweaty just before Barbarossa and during the early stages because I know, 9 times out of 10 it will lead to my eventual downfall. I bet my blood pressure even shoots up for that period too. how much would that suck if I died of a heart attack while playing HOI?
I play WiF, which discourages you from invading before June 1, 1941 due to ruining subsequent scripted events. Although there is a June 1st Barbarossa event that sometimes fires. Fighting the Soviets in WiF is 10 times more difficult than in Vanilla. I almost always bog down around the Dnieper River just before the first winter.
