Design a digital game store like Steam

Design a digital game distribution platform like Steam. Players use a desktop client to browse a store, buy games, see what they own in a library, and download, install and update those games. Developers publish games and release new builds.

Cover the catalog and store, purchases and ownership, how large game files and updates reach players quickly (content delivery, patches instead of full downloads), how developers ship builds, and the peaks around a big release or sale.
