Namely, I hate it that I know how events are going to unfold in the game because they have been historically scripted to do so. This is just annoying. If I choose to use that information, I can wait to research a few techs because I'll get them as part of the Condor legion returning home event and I can wait about 3 days before queuing up a factory build until the reoocupation event fires and I get +1 hawk and I can hold off on building more troops because I get some when I annex Austria and Czech. I can hold off building any troops until late '38 or early '39 and just queue factories to give me more production, higher tech and more TC for the attack on the USSR that will happen in '41. That is just as Germany, every major country has these kinds of events and strategies that are "historical" but just gamey.
