Our friends over at Night Dive Studios recently released the classic adventure game, "I have No Mouth, and I Must Scream" on GOG.com. Based on Harlan Ellison's book, this game takes the players through a dystopian world where a rouge AI kills all but 5 people. Over the course of the game you have to make choices that prove humanity's superiority to computers. It's a really compelling game that weaves in lots of social elements to make this very interesting classic game.
