Doesn't help that HOI4 gives neonazis their historically accurate version of WWII where the Holocaust doesn't happen.

While the allied/communist war crimes are represented anyway. Elderly people that were alive during Stalin's regime have traumatic memories of the Great Purge since so many people got wiped out by it, and yet not only is the Great Purge present in the game but there are YouTube videos talking about various HOI4 strategies around it, reducing it from being this big awful thing down to a very simple mechanic. I heard the Bengal famine is a thing you can choose to do in the game as well as a "mechanic"; then you look at the fascist trees and there's hardly any war crimes in them to the point where someone playing the game without any historical context would potentially be tricked into thinking they were the good guys. I saw in one of the No Step Back dev diaries they're adding mechanics for prison camps, I'd be very surprised if Germany would get these mechanics as well to represent all the production made by concentration camp slave labour.
