Beginning in early September, Valve is making some changes to "what can and cannot be included" in Steam store page descriptions, ruling out links to other websites, embeds that mimic Steam store UI, and links or embeds to other games on Steam.
A fresh Steamworks Development post outlines the new rules, targeting four areas of Store pages: About The Game, Short Description, Special Announcements, and Awards. "We'll be enforcing new rules for what can and cannot be included in your written store page descriptions," it begins. Valve says this is partly a follow-up to a previous change about demo visibility on the storefront, which gave demos their own separate pages and let them behave like free games in store lists.
