It might be a few side stories, but it all makes it feel more complete.

Doki Doki Literature Club was once a hidden gem on Steam when it first launched in 2017. The seemingly innocuous and free-to-play visual novel about a student who joins a literature club filled with dateable prospects became famous because it was everything but what it said on the tin. This dating sim was actually not a dating sim at all, but a horror game, and the transition from poppy visual novel to dark, gruesome tale made for some of the most emotionally impactful gaming in recent memory. It's not surprising then that it's gone on to become a cult favorite among horror aficionados.
