In various examples, metadata of either a live stream game instance or a pre-recorded game instance may be included in a stream data from a game stream and used to enable access to play an instance of a game. A viewer of the stream may desire to participate in an instance of the game, and the system may use the metadata to determine authentication for the viewer with respect to a game platform hosting the game, access restrictions for the viewer with respect to the game, identification information for the streamer of the instance of the game, and/or game modification information for the particular instance of the game within the stream. This information may be used to seamlessly transition the viewer from a passive role in viewing the stream of the instance of the game on a streaming platform to actively participating in the instance of the game or another instance of the game on a gaming platform.
