For anyone interested in getting a vague sense of what it might have been like to be Mikhail Gorbachev there is a pretty low-fi simulator game called Crisis in the Kremlin on Steam.
I played through it and it requires juggling the various factions in Soviet Russia. I ended up getting couped by the military but just reading the various prompts and choosing where to put resources gave me a better understanding of the dilemmas anyone in power in the USSR might have been going through.
I can't attest to whatever bias might have been embedded in the game mechanics but it was interesting. Actually I only played the 2017 re-make. I didn't realize there was an original game from 1991. https://en.m.wikipedia.org/wiki/Crisis_in_the_Kremlin
