Valve updated its Steamworks Documentation to include a dedicated "Advertising on Steam" page, formalizing its existing policy against advertising on the platform. The new page clarifies that Steam does not support paid advertisements or referral revenue from ads for other games or products. Developers whose games rely on advertising must consider alternative monetization strategies, such as a single purchase model or a free-to-play format with microtransactions or downloadable content (DLC). Models that block customers and require payment to continue playing are prohibited, and developers are encouraged to offer free demos. Valve has also consistently banned games that utilize blockchain technologies, including cryptocurrencies and NFTs, to maintain a safe gaming environment.
