During the second day of Nintendo's E3 stream, Nintendo has announced a brand new 3DS RPG titled Ever Oasis. It is being developed by Grezzo, who is most well known for porting the N64 Legend of Zelda games to 3DS. In the game, you play as a character who starts an Oasis in the middle of the desert and works to both build their town and conquer dungeons. The game has multiple playable races with different abilities, and control can be switched between characters easily during combat. The game is being directed by Koichi Ishii, who also directed Secret of Mana and Final Fantasy XI.
