My sons (ages 7 & 6) finished this game in a single afternoon. Worse yet, they showed no interest in replaying it, making Toy Story 3 my most expensive DS purchase. A good game can last weeks, even months with repeated play. Geez, we still have two copies of Mario Kart and we purchased them nearly two years ago!
The story mode mixes adventure play and mini-games. Beware though, story mode is very short. The game offers two other modes - Imaginary World and Playtime. The game also includes DGamer features for online play, including special achievements that can be unlocked and shared with friends.
Of course, none of these extras appealed to my kids. I attribute part of the problem to the fact that my sons were born *after* Toy Story and Toy Story 2. They have no nostalgia for Woody and Buzz. So, the game had to win them over on its own merits.
Even the large cache of unlockables available wasn't enough to entice them to play the game again once they finished the story mode.
What caught my attention immediately was the voice work and background music. Woody, in particular, went from cute to excruciating annoying inside of 15 minutes. He repeated the same lines repeatedly in a higher pitch than I remembered from the movies. His voice in the game version reminded me of something you might hear from a fortune teller coin-op.
I want to note that the game looks good (the game trailer was part of the reason I bought the game in the first place). The 3D environment is trippy and surprisingly easy to navigate.
In summary, the story mode is very short. Make sure your kids are huge fans of the Toy Story trilogy before making this purchase. The game's value will depend on their play of the other two modes - Imaginary World and Playtime - and an interest in searching out all of the unlockables. For our sons, this game couldn't hold their interest for a second day. Rating: two stars.
