Edition upgrade
Edition Upgrade indicates a downloadable content (DLC) which acts like a patch or and update that basically upgrade the base game release to limited or deluxe or special edition release. It adds all the content difference between base and special edition release. Sometimes the content includes additional in-game elements while other times this can be a set of bonus content like digital art book or soundtrack or set of avatars.
Important: Similarly to how DLCs that add just non-game elements like digital soundtrack or digital art book that are accessible on their own and are not integrated inside the game itself, edition upgrades that only add such content are also not accepted as game entries. In order to DLCs or edition upgrades with only non-game elements, those elements must be integrated in the game and must be accessible either via main menu or pause menu or any other in-game interface.
