Caves of Qud: Diaspora tests a Steam Early Access path for DLC

Game Developer reports that the expansion is the first DLC released through Steam Early Access. The base game and expansion have different completion states.

The launch separates an established game from an expansion still being developed with player feedback. That creates a useful case for publishers planning longer post-launch roadmaps: customers need to understand exactly which content is unfinished and what a purchase includes. This example does not establish that every developer can enable the same arrangement automatically. Teams considering it should confirm their own Steamworks options and present the development status clearly.
