Have you checked out I Have No Mouth And I Must Scream, the bizarre and genuinely disturbing ‘90s adventure game based on Harlan Ellison’s short story about the worst-case endgame for artificial intelligence? No? It’s currently $1.49 in GOG’s winter sale, so if you missed the free giveaway for it last year there’s no better time to change that. I played it a few years ago, and it’s a fascinating piece of retro gaming... but I don’t regret using a walkthrough for some puzzles.
