Some games that came to mind for this thread were:

• Another Crab’s Treasure, a soulslike with some fun imagery, but also a great storyline about the poisons of late-stage capitalism
• Mouthwashing, the famous horror game where the monster is machismo and warped senses of responsibility
• J J Macfeld and the Island of Memories, also a pretty brutal game about a certain kind of social acceptance (I got this one wrong even late-game, which made its message all the better)
• Papers Please, giving you a highlight of the xenophobia developed at the border of nations in conflict
• Celeste, promoting self-acceptance through difficult platforming challenges
