Microsoft trained an AI model on a game no one played

AI algorithms capable of generating simulated environments -- represent one forefront of machine learning. Today, Microsoft published new research in the journal Nature detailing Muse, a model capable of generating game visuals and controller inputs. Unexpectedly, it was born out of a training set Microsoft built from Bleeding Edge. If, like me, you had completely erased that game from your memory (or never knew it existed in the first place), Bleeding Edge is a 4 vs. 4 brawler developed by Ninja Theory, the studio better known for its work on the Hellblade series. Ninja Theory stopped updating Bleeding Edge less than a year after release, but Microsoft included a clause in the game's EULA that gave it permission to record games people played online.
