There’s a decent chance you’ve never heard of the Square Enix DS title, Nanashi no Game](http://nintendo.joystiq.com/tag/nanashi-no-game) (roughly: The Game with No Name), as it was never released outside of Japan. Essentially, it’s The Ring in video game form. In the original Nanashi no Game, the player was introduced to a cursed role-playing game that killed its players within seven days if they failed to complete it. Thus, the game was split into sections of first-person exploration in 3D and sections that were styled after 8-bit role-playing games of yore (Dragon Quest, most notably).
The trailer looks interesting. Even if they don't officially release it in North America, DS games don't have region protection.
