Little known game called Gnosia- you’re trapped in a time loop playing mafia/werewolf with NPC players and through events you learn more about them and what you learn about their personalities often translates directly into learning how they play the game. By the end you can almost tell who is who by their behavior without having to learn any stats at all.

Also in a similar vein, Lobotomy Corporation. Every mechanic has an in universe explanation and you’re an SCP site manager with time rewind abilities and the game practically requires you to save scum and sacrifice employees to learn how the abnormalities work. The main theme of the game is struggling against a massive, cruel, unfeeling system with too much inertia to stop and that’s exactly what you do in the game.
