Another angle: sometimes beta versions have bugs or incomplete features that are fixed in the final game. The user might be interested in exploring these early versions for nostalgia or to see the game's early development. The exclusive content could include characters, moves, or features that were cut during the final release. It's worth mentioning any specific exclusives if known, like maybe certain characters or game modes that were present in beta 13 but not in the final version of the game.
