the USSR focused DLC for HOI4 has a mechanic around the Great Purge where "Stalin's Paranoia" is gamified, you essentially have to purge random generals in the game to keep "Stalin's Paranoia" down but the funny thing is if you ignore this mechanic, trotsky comes back and coups you lol, so i have zero idea what sort of political message paradox is making. So Stalin was bad for randomly killing people but he was actually proven right in the end?
bear in mind that this is the game that still refuses to model anything bad that Axis does (holocaust etc) or anything bad that the western allies do (bengal famine etc)
