Classic Game Room HD reviews MY SECRET DIARY for Nintendo DS. This game is aimed at pre-teen girls who want to keep a secret diary, enter contacts and play mini games! Wowee! Basically all the same things that a cell phone can do except this is played on Nintendo DS. My Secret Diary is checkout, impulse purchase fodder for parents who don't know any better. While the game does what it claims it to do it doesn't do much. Enter a password, play with the mood sensing jewel thingie and visit the word garden. My Secret Diary is best left as a secret.
