Valve Developers Quietly Testing AI for Game Writing, But Threat to Writers Remains Distant
A small group at Valve is experimenting with generative AI tools for video game writing, according to Erik Wolpaw, the writer behind Half-Life 2 and Portal. Wolpaw said the technology is currently "pretty bad" at creative writing and poses no near-term threat to human authors.
Wolpaw discussed the experiments during a recent MinnMax podcast episode. He emphasized that Valve's efforts are informal and exploratory, not a company-wide initiative. "Let it be known far and wide that this is not a concerted Valve thing," he said. "It's just about finding the best practices for the technology we currently have access to."
AI Falls Short on Creative Work
Wolpaw compared current generative AI to chess bots. The best chess players in the world can still beat them, and he expects the same will hold true for creative writing. "I'm currently not worried about AI taking over creative writing because it is pretty bad at it," he said.
He added that the team has tested the tools extensively. "We've really been messing around with it," Wolpaw said. "I don't think it's going to-any time soon-be writing novels that are better than those written by humans."
Where AI Might Actually Help
Wolpaw sees more potential for AI in a specific area of game development: real-time NPC dialogue. Unlike movies or novels, games require characters to react instantly to whatever a player does.
He pointed to Left 4 Dead as an example. In that game, certain actions trigger specific voice lines from characters. "The only place where I feel like AI is worth investigating is game writing," Wolpaw said, referring to these reactive dialogue systems.
If developers throw enough human writers at a game, they can create dialogue for almost any scenario. But scaling reactive systems across countless player actions remains resource-intensive. AI tools could potentially help generate variations of character responses to different player choices.
Exploratory, Not Imminent
Wolpaw stressed that Valve's work remains in early stages. The developers involved are simply exploring whether the technology warrants further investigation. No formal company strategy around AI for writing exists yet.
For writers concerned about generative AI and LLM tools, Wolpaw's assessment offers some reassurance. The current generation of AI still struggles with the nuance, voice, and originality that define strong creative writing.
