A Steam demo needs a release checklist of its own

A demo represents a promise about the full game, but it is also a separate release to configure and maintain. Valve's documentation assigns demos their own application ID, linked to the base game, with builds and a release checklist.

Developers can keep the demo's presence on the main game's page or create a separate store page. If they choose a separate page, its descriptions, screenshots and feature lists need to represent the playable demo accurately.

That matters when a demo supports fewer languages, modes or features than the commercial product. A store page that describes the full game without making the distinction can set the wrong expectation before the first launch.

Valve also documents options for sharing content depots and cloud saves, which can reduce friction when a player moves to the released full game.

The editorial recommendation is to review the entire transition: discover the demo, install it, understand where it ends and find the full game. The amount of content is only one part of that journey.
