Valve quietly updates Steam's rules to ban games “built on blockchain technology that issue or allow exchange of cryptocurrencies or NFTs”
Your move, Epic Games Store — Games that use blockchain technology or let users exchange NFTs or cryptocurrencies won't be allowed on Steam … Source: Steamworks Documentation .
Context & Ripple Effects
Steam's 2018 posture was to admit games unless they were illegal or trolling; the new rule is a concrete retreat from that broad default for titles using exchangeable crypto assets, despite the earlier promise of more user-controlled filtering. Steam's earlier all-but-illegal-or-trolling standard is now paired with a categorical technology-based exclusion.
The later dispute over copyright-infringing AI artwork places this in a wider pattern: Valve is drawing publication boundaries around inputs and systems it considers unacceptable, rather than treating every game as a neutral listing decision.
First-order effects
- Developers whose games issue or permit exchanges of cryptocurrencies or NFTs lose Steam as a distribution channel, and Steam users cannot obtain those titles through the store.
- Epic Games Store becomes the named PC-store rival most directly tested by developers seeking an alternative outlet, although the coverage does not establish Epic's own policy.
Second-order effects
- Blockchain-game publishers must design around Steam's rule or concentrate distribution and community-building on storefronts that accept their model, increasing the strategic value of rival PC channels.
- Steam's policy gives conventional PC-game publishers a clearer assurance that marketplace discovery will not mix their releases with games built around exchangeable crypto assets.
Third-order effects
- If Valve applies the same approach across emerging technologies, PC-game distribution shifts further toward storefronts deciding which technical and economic models may reach their audiences, not merely policing illegal or trolling content.
- The contrast with Steam's earlier permissive policy suggests platform access can turn on category-specific rules as new game-production and monetization methods emerge.
The trend: PC game storefronts are moving from broad content-hosting rules toward active gatekeeping of the technologies and asset systems embedded in games.
