Coming at this from an IT perspective, a lot of things that people “already know” seem to evaporate when it’s time to actually apply that knowledge. Keeping that in mind, I think a game like this helps to cement the idea in people’s heads in a more intuitive way. It bridges the gap between system 1 and system 2 thinking.
The main character starts the game literally giving himself a traumatic brain injury by drowning himself in alcohol. It’s not really the kind of RPG where you can play a self-insert, the player character is an actual character with his own backstory. Not being able to make good choices because of the player character’s personal trauma and limitations is part of the story that the game is telling.
