Set three years after the original Final Fantasy 2, "Genesis of the Dark Crystals" serves as a lead-in to the rest of the series using the established world and characters of Final Fantasy II as a basis. Dungeon layouts, enemies, and music are borrowed from the first six games, in addition to emulation of FF2's skill mastery system, with select modifications and enhancements for improved playability.

　　Featuring more than 20 hours of gameplay, "Final Fantasy 2-2: Genesis of the Dark Crystals" begins with the selection of three scenarios, followed by an expansion of the world characterized by free-roaming, that ultimately culminates in a mirrored, cooperative effort to resolve the conflict (a la "Soul of Rebirth"). Highly replayable due to the open-ended nature of the character progression, the game seeks to realize what was set out to be accomplished by the original team. It serves as a window into the "what-if" scenario of FF2 being the foundation for the future of the series. It is a love letter to the original game, and FF as a whole, penned by someone who cherished it greatly and wished to see its full potential come to fruition.
