The relatively unheard-of studio Ocelot Society did the impossible with Event0: they made a chatbot interesting. Set within the standard but comforting framework of a claustrophobic spaceship exploration game, Event0 is really about building a relationship between the player and the ship-bound AI, a chatbot named Kaizen. Being able to see the limitations of Kaizen's technology (basically the same stuff that's been used since we were all tooling around with AIM bots a decade ago) doesn't stop him from being a convincing and sympathetic companion as you try to figure out how to return to Earth. Kaizen may not be trustworthy, but that just makes him all the more bewitching.
