Nintendo has unveiled the New IP RPG / Adventure title for 3DS, and it's called Ever Oasis. In development by Grezzo (well known for the 3D Legend of Zelda remasters on 3DS, for example), the project is being led by Koichi Ishii. Ishii-san played a key role in early Final Fantasy titles, and directed the Mana series up to 2006. He also served as producer on the aforementioned 3DS Legend of Zelda remasters.
As for the game itself, the Nintendo Treehouse demonstration has shown a colourful setting with a strong 'Egyptian' inspiration; there are aspects of growing resources and attracting wanderers to your Oasis in order to expand. The initial trailer also showed fairly conventional adventure RPG exploration and real-time combat, with the camera mostly locked behind the player. One feature is that you have a party of characters with different abilities that you can swap between on the fly; dungeons, puzzles and boss fights are also prominent.
At the time of writing it's still being demonstrated on the Nintendo Treehouse live stream, and you can see the trailer below.
