This came with my DS, and is not a title I would probably have picked for myself. However, I am enjoying playing my way through it (I'm about 70% of the way through),and have found it good to get used to using my new console. For the accomplished gamer, I would say it is probably going to be far too easy for them. However, for casual gamers and fans of the film, I'd say it was a worthy investment. With two modes - story (a 3D platformer) and cooking (where you cook up recipes in the kitchen using the DS's touch screen), you can be entertained by Ratatouille for as little or as long as you like.
Great fun!
