The term "repack" in the context of game distribution refers to a re-packaged version of a game, often optimized for digital distribution outside of official channels like the eShop. A repack might include game data that has been compressed or rearranged to make it more suitable for downloading or to bypass certain restrictions. For Monster Hunter Rise Sunbreak, an eShop repack implies a version of the game that has been prepared for distribution outside of the official Nintendo eShop, potentially offering a more straightforward way to obtain the game for players in certain regions or with specific preferences.
