Steam Next Fest charts 10 top demos, but only 1 has an AI disclosure

Valve has revealed the ten most played Steam Next Fest demos, and the surprise is blunt: only Embers of the Uncrowned, among those top played entries, carries an AI disclosure. The other nine top demos in Valve's list, spanning games like Bandai Namco's Echoes of Aincrad and the offroading sim by the creators of Art of Rally, show no such AI disclosure in the way the PC Gamer piece is describing it.

That single AI disclosure matters because it lands in the middle of a much larger AI labeling reality on Steam. PC Gamer points out that SteamDB shows 4,397 products listed as Next Fest demos, with 551 having the AI Content Disclosed user tag attached. In other words: in the broader Next Fest pool, AI labeling is already relatively widespread. But in Valve's top played subset, it barely shows up.

So what is the top ten, and why does it look the way it does? According to PC Gamer, Valve’s list includes Echoes of Aincrad, described as an anime third-person ARPG set in the Sword Art Online world; Mistfall Hunter, an extraction RPG that swaps typical shooting for Soulslike third-person combat; and IRON NEST: Heavy Turret Simulator, a heavy turret simulator. The list also features IRON NEST’s adjacent ecosystem of action and formats, including EMPULSE, a 6v6 shooter by the creators of Splitgate; Dust Front RTS, a vintage-looking RTS for '90s PC gaming heads; and The Mound: Omen of Cthulhu, a four-player co-op about scouring a dangerous, slightly sci-fi jungle for treasure.

On the lighter end, PC Gamer highlights Embers of the Uncrowned as the next Nexon MMO in the set, plus BOMBANANA!, a whimsical friendslop about monkeys defusing bombs. The final entry is Casualties: Unknown, a survival platformer about exploring a murky, dangerous subterranea. PC Gamer’s own reaction is telling for executives, even if it’s framed as personal: they say they are especially keen to try Casualties: Unknown and Over the Hill, and they call out the absence of Mortal Shell 2 as notable. They also express surprise that Valor Mortis, the new first-person Soulslike by Ghostrunner devs, is not listed.

But the core business and strategy issue is not whether these are good demos. It is how developers, publishers, and Valve are co-existing with AI transparency signals at scale. PC Gamer quotes the AI disclosure text for Embers of the Uncrowned, attributed as coming from Nexon’s disclosure. The disclosure says that during development and live service, AI-based tools may be utilized to support in-game visual content creation, marketing materials, live chat translation features, and partial in-game dialogue and script localization. It also adds that regardless of workflow, the final product is a reflection of the development team's creativity and artistic expression.

This is where the second-order effect shows up for leadership teams. If only one top demo in Valve's “most played” slice has an explicit AI disclosure, users who care about AI may either (a) assume the rest of the field is “clean,” or (b) get trained to hunt labels specifically on Steam store pages. PC Gamer says exactly that: while browsing Next Fest, they fell into the habit of scrolling directly to where the AI disclosure normally sits on a Steam store page without reading the description, watching the start of the trailer, or looking at a screenshot. They argue it is not a brilliant user experience, and they connect it to how common antipathy towards AI in games seems to be.

From a platform risk and revenue angle, the “labeling gap” matters. Steam is showing AI disclosures in the wider demo marketplace at non-trivial rates, but the most visible and most played demos are not evenly labeled. PC Gamer also brings in release data for context: last week over 300 games were released on Steam, and 120 of them had AI disclosures. If that cadence persists, the labeling will become the default part of a consumer scan, even if a subset of top-performing demos is not using the label consistently.

For boards, publishers, and studios with live service roadmaps, this has two strategic implications. First, AI labeling is no longer a niche compliance detail. PC Gamer frames it as a “floodgates are open” moment, not necessarily with panic, but with scale: 120 releases with AI disclosures in a week alongside 551 Next Fest demos with AI tags. Second, the mismatch between how often AI disclosures appear in the catalog and how often they show up among the most played demos can distort user behavior. If players learn to ignore trailers and screenshots to check labels, marketing and community engagement get rerouted away from content toward disclosure verification.

Valve included a filter is PC Gamer’s suggested fix, but the larger takeaway for executive teams is simpler: user attention is finite, and labels compete with gameplay. When antipathy towards AI exists, the presence or absence of an AI disclosure can influence whether a player clicks, watches, refunds later, or posts. The top ten Next Fest demos being dominated by non-disclosed entries, while AI disclosures exist across hundreds of demos, sets the stage for discoverability and trust dynamics that will matter for every publisher launching demos, updates, and new live service content this year.
