Harvest Moon creator Yasuhiro Wada and publisher Natsume revealed their next project together at E3. "Project Happiness" is a new IP in which you run a shop in a small village, buying and selling items to improve the shop and learning the stories of all the customers who come in over the years. Natsume later revealed plans to put it on 3DS and mobile; during an interview at E3, Wada said it was planned for a "variety of platforms."

Wada recruited top talent to create his new game. Character designs, for both humans and the adorable "sprite" creatures that inhabit the world, are by Pokemon character designer Atsuko Nishida. The music, including that heard in the above trailer, is composed by legendary Final Fantasy series composer Nobuo Uematsu.
