Another Eden

Despite being a mobile game created on the GREE platform, the game has little focus on social interactions and log-in bonuses frequently found on the platform. The game is free to play, with in-app purchases for in-game items. The game features an 114-chapter main scenario that continues to grow, with the gameplay involving the player time travelling through three main time periods; the past, present, and future.

The game primarily plays as a side-scrolling JRPG, at times opening up for full 3D movement. The player directly maneuvers a character between locations and interacts with non-playable characters to progress through the game. Confrontations with enemy characters are played out with turn-based battles. New characters will join the party and grow stronger naturally over the course of the game flow, however the player may opt to spend "Chronos Stones" to obtain a larger roster of characters to use throughout the game. "Chronos Stones", which can be obtained naturally through playing the game, or bought through in-app purchases, allows access to the "Star Dreaming Hall", which allows the player to gamble gacha-style for a wide variety of characters.

The game centers around a boy named Aldo, the game's protagonist, and his sister, Feinne. The two live plain and peaceful lives in a small village; however, one day, the Beast King appears and seeks to use Feinne's dormant abilities to erase humans from the world, leaving the planet only for beast-kin. Aldo desperately attempts to rescue his sister from the Beast King, but a distortion in space-time occurs in the air and whisks Aldo away 800 years into the future.

Development on the game started in early 2015, with its first announcement occurring in September 2015, at that year's Tokyo Game Show. The game was revealed as a new project by Masato Kato, who had written and directed Chrono Cross, and wrote parts of Xenogears and Chrono Trigger. The game was developed by Wright Flyer Studios for iOS and Android devices on the GREE, Inc. platform, with Kato directing and writing the game's scenario and script.

Kato collaborated with GREE producer Daisuke Takasaki, who previously worked on Puyo Puyo Quest, on the game, as they shared the same vision of putting a more traditional JRPG on mobile device, something Takasaki felt the platform generally lacked. Importance was placed on making free-range movement comfortable on button-less devices, something Takasaki felt was poorly, or not at all, implemented on many mobile RPGs. Graphics were kept two dimensional to help accommodate the game's large scope, with 2D graphics being cheaper and easier to create on a larger scale. This was necessary to realize Kato's large scope for the game's story as well.

RPG Site praised the original Japanese release of the game, stating that despite it being on mobile devices, it still played like a "fun, traditional RPG" and that they could "barely call it a free-to-play game. The annoying trappings (like stamina and timers) are almost nonexistent". They also gave praise to the graphics, soundtrack, and post-release game updates.
