I wrote earlier about a neural net-powered dungeon crawling text adventure game called GPT-2-Adventure in which gameplay is incoherent and dreamlike, as you encounter slippery sign text, circular passages, and unexpected lozenge rooms. A PhD student named Nathan trained the neural net on classic dungeon crawling games, and playing it is strangely surreal, repetitive, and mesmerizing, like dreaming about playing one of the games it was trained on.
Now, building on these ideas (and on an earlier choose-your-own-adventure-style game he built), Nick Walton has built a new dungeon-crawling game called AI Dungeon 2. Nick made a few upgrades, such as beefing up the AI to the huge GPT-2-1.5B model OpenAI recently released, adding a penalty for repetitive text, and expanding the dungeon game training examples to a bunch of modern human-written games from chooseyourstory.com.
I CAN’T STOP PLAYING THIS GAME
