AI in Games: Generative NPCs, Assets and Steam Rules — 2026-09-28
This week's big stories: PC Gamer documents a new wave of Steam "haystack slop" amid rising AI disclosure volumes, Microsoft patents AI that rewrites games dynamically based on player behavior, and a fresh roundup catalogs every shipped game with free-form AI NPCs you can talk to. Player backlash over small amounts of AI use continues to weigh on indie launches.

PC Gamer: "haystack slop" lands on Steam
PC Gamer's Steam Week in Review for the week ending September 27 coins "haystack slop" as the latest AI-content phenomenon on the storefront, part of ongoing coverage of how a "touch of AI" is enough to trigger player backlash against otherwise promising indie releases. The piece underscores how disclosure tags are increasingly shaping community reception and review behavior.
Microsoft patents AI-powered dynamic game rewriting for Xbox
A Microsoft patent filing reported September 25 describes generative AI that modifies narrative-driven games after launch in response to individual player behavior — potentially affecting story, content and world state on future Xbox titles. If it moves from patent to product, it would raise new disclosure questions: content that changes per player sits squarely in the live-generated category regulators and platform policies are still catching up with.
Verified roundup of games with free-form AI NPCs
Arcanum RPGs published (September 26) a verified list of games where NPCs answer anything you say rather than following dialogue menus — including Where Winds Meet, inZOI, Whispers from the Star, Suck Up!, Vaudeville, Verbal Verdict and AI Roguelite — checking each against its own Steam AI disclosure or technology partner. It's a useful snapshot of which conversational-NPC implementations actually shipped versus marketing claims, and how each is disclosed on Steam.
MiHoYo's AI ambitions under scrutiny amid GDC 2026 survey data
A Chinese investment-analysis piece (September 27) examines miHoYo's AI strategy across three parallel tracks, citing GDC 2026 survey data that 36% of game professionals use generative AI while 52% believe it is hurting the industry. The tension — personalization vs. mass-produced story and art — mirrors the player-backlash dynamics seen on Steam this week.
Local view
Japanese-language coverage continues to frame the AI NPC debate around Square Enix: the conversational AI buddy "Oshaberi Slamy" in Dragon Quest X Online (built with Google Cloud's Gemini 2.5 Flash) remains the reference case, with outlets like Realsound and AI teller debating whether generative NPCs genuinely make games more fun. CNET Japan's coverage of the Microsoft patent (September 25) adds a domestic angle to the dynamic-content discussion.
Context & numbers
- The GDC 2026 State of the Game Industry survey puts personal generative AI use at 36% of professionals, with 52% seeing negative industry impact
- Visual/asset generation accounts for roughly 60% of disclosed uses in Steam AI disclosures, the single largest category
- One 2026 tracker put the end-2025 total at 4,311 Steam games carrying AI content disclosures, a 100% increase from 2024
- Epic, PlayStation, Xbox and Nintendo still have no equivalent AI disclosure rule to Steam's
On the radar
- Watch for follow-up on "haystack slop" — whether the term (games burying minimal AI content in huge files) becomes a recurring backlashing pattern heading into the Q4 release season
- Microsoft's dynamic-game-rewriting patent: patent filings rarely equal shipped products, but any future Xbox filing-to-product move would test disclosure rules on live-generated narrative
