I spoke about Yasuhiro Wada’s new game, Project Happiness, the other day, but at that point it hadn’t been announced for any specific consoles. Since then, Rising Star Games has officially announced that the game will be on 3DS.
Neither a Japanese nor US release date has been given yet, but my best guess is that it will be out sometime next year. Regardless, this is definitely something 3DS owners can look forward to.
