Atelier Meruru: The Apprentice of Arland, part three of Gust's Atelier trilogy, is currently being localized for western audiences and prepped for launch by NIS in North America and Europe this May. NIS also published the first and second entries in the series, Atelier Rorona: The Alchemist of Arland and Atelier Totori: The Adventurer of Arland.
As the artful trailer above explains, Atelier Meruru concerns the adventures of Princess Meruru and her quest to become an alchemist while simultaneously growing her kingdom of Arls to its full potential. "Development" is a primary aspect of the gameplay, with story progression changing based on how the player decides to expand and improve the kingdom. Personally, we had no idea that becoming a master alchemist involved so much sweeping.
