Doki Doki Literature Club is one of those games considered genre-defining, as it almost singlehandedly spearheaded and revolutionized the "new weird" movement in video games, where titles would behave seemingly on their own, providing some of the most unique horror ever displayed on screen.
It came out in 2017 and at the time was surrounded by a lot of controversy and discussions, primarily due to its dark, graphic, and unfiltered themes that concerned suicide, self-harm, mental illness, and so on. It was and remains a direct confrontation with the darkest sides of humanity and is, on top of that, one of the most unique games ever made, since its gameplay loop largely depends on constant replays where the game "autonomously" does things to itself and to your machine.
