I loved this game on my DS when I got it early in the DS's lifespan, it had a foreboding but beautiful atmosphere, a mysterious story, a serene soundtrack, and ofc likeable characters. So I was very happy when I learned that a sequel had been made for the Wii in 2009, called Another Code: R - A Journey into Lost Memories (only released in Japan and Europe though). This game brought back most-everything I had come to love about the first game... but sadly it sold poorly, and thus a 3rd game to conclude the loose ends from AC:R is very unlikely to ever be made.
The game is an adventure/puzzle visuel-novel, and I really honestly believe it deserves more attention than it has gotten, it's a game with a lot of heart, and I strongly recommend any fan of the above mentioned genre to check it out - if you haven't ofc ^_^
Here are two of my favorite tracks from the first game:
