A homebrew developer is recreating the original NES Metroid game to work on the Game Boy, in the same vein as Metroid 2: Return of Samus. The original Metroid is a classic series that established a formula of exploration and is regularly praised by fans of the series, even if not every aspect of the title has aged gracefully. The Metroid series is a common subject for those looking to make fan games, regardless of whether said games come in the form of an older adventure being remade or a brand-new one being created.
