If your kid lives to sing HSM songs - they'll enjoy it -but odd menus, and not using the original cast reduces the fun
Positives of the game - very forgiving for little singers with no "grades" below a "C" on any song you try - no matter how "creatively" you sing... For older singers, the karaoke aspects work cleanly - nice visuals for how long to hold notes and relative pitch progressions on screen. A cute little basketball bounces up and down (even when vibrato-ing) to show you when you are on track, and little encourging grades throughout the song showing how you are doing.
Now some of the disappointments:
* They don't use the original cast for many of the songs - Zach Efron's voice is missing from many of the songs and someone else is used - which my kids noticed right away. Considering that the original voices are so well-known, and the characters pictures are used in the game graphics - it borders on deceptive advertising.
* For many of the duet songs, as a soloist you are forced to sing whichever is the 1st singer - no matter if it a boy or girl part. My daughter was extremely frustrated (as were we) to not be able to sing Gabriela's parts when she wanted to.
* There are some menu and control oddities - especially around editing characters. Not real inituitive given the likely audience of young kids playing this. I doubt any focus groups were used... Again - Disney normally does such a great job on this type of thing - it seems this was rushed to production to capitalize on the movies rather than make a more fun game...
