I just finished Another Code: R not long ago... very well made game, was a lot longer than its DS prequel.... but when it was all over, I was a little sad knowing what's happening to Cing. I feel like this is a series that could've gone on for at least one more game...
...though at the end of the game I did notice that the Executive Producer listing was Satoru Iwata, the President of Nintendo... and the copyright notices said that everything was owned by Nintendo...
Nintendo may hold the rights, but if these games aren't made by the people who make up Cing then I can't see them being as special as they are.
