I rented this for the trophies alone and they keep coming and coming! I played through the entire game and scored all of the trophies in five hours, minus the one where you need to play the pony race at the carnival with three friends in real life, not simulated in game, nor online, so if you don't have three other people with PS3's that can come to your home you'll never score the platinum trophy for this game.
This game is great for my pre teen and teen daughters and myself, their dad too.
If you are renting this game, most likely, you are aware that it is around a 3 to 4 hour platinum trophy. Aside from this, there are not many redeeming qualities to this title. With forced Sixaxis control and terrible mini games this game is a tough sell for even the most hardcore Hannah Montana fans.
