Polygon - Gaming's favorite villain is mental illness, and this needs to stop.
If you encounter a game that deals with issues of mental health, chances are it’s a horror game. The genre loves to play around with mental illness; specifically the vague, generalized Saturday Morning Cartoon-style "insanity" that doesn’t match any real definition of the term. In fact, the concept of sanity is so ubiquitous within the genre as a thematic, narrative and mechanical device that several horror games feature [in]famous "sanity meters;" literally a way to quantify how "crazy" characters are.
