Games that use blockchain technology or let users exchange NFTs or cryptocurrencies won’t be allowed on Steam, according to a rule added to Valve’s “What you shouldn’t publish on Steam” list. The change was pointed out by SpacePirate, a developer working on an NFT-based game, who said that the change was because the company doesn’t allow game items that could have real-world value. But Steam could also be avoiding controversy with the move.
Looking at a Wayback Machine capture of the rule page from late August, there are only 12 rules and no mention of cryptocurrencies or NFTs. The new rule is also missing from other documents — it currently doesn’t show up on the Joining the Steamworks Distribution Program page.
