Slavoj would design an open world sandbox game that models various different competing state power structures. Actual gameplay would be the confusing, almost existential horror of attemtping to navigate within these monoliths of ideology with the only real hope some glimmer of creating a better system. Likely most of the time you'd just spend in the tavern making grotesque jokes about eachothers mothers, drinking and talking politics into the night. It would try to answer, 'what do we do the day after the revolution?'
Peterson would run a traditional, railroaded fantasy game about a group leaving their village, venturing across the chaotic wastes, slaying a great serpent that represents their mother and restoring order to the wastes as a result, then returning home, banging a princess and becoming redpill.
Slajov's game would be the far more interesting and engaging one that actually has the ability to uncover real truth about society, ideology and power but it would actually be challenging, confusing and difficult so people would ignore it.
Peterson's game would have the most mass appeal to the simple player as it tells an easy to understand and play out biblical narrative of good vs evil , chaos vs order and feels comforting as a result. It is of course also a comforting lie that conceals the truth. Peterson knows this but believes it's better for you, and therefore society, because he thinks you are stupid, to believe this lie.
