Basically, Sanitarium is about a man suffering from amnesia. The game plays through delusions he is having while in a mental institution. More info here. This was always one of my favorite games to play and I would love for pewdie to play it mostly because it really messes with your head. It can be bought here (if being legal is your thing :P)

Appologies, didn't see it when I scanned the list. And as for the template....I forgot I needed one lol
