I bought this for my 3 1/2-year-old daughter, a huge Toy Story fan who has loved playing with the cartridge that came with her MobiGo.
There are four simple games here, and then there are two that are hard, even on the "easy" level. That ticked me off-- the one featuring Woody is probably the hardest game, and of course, that's the one my daughter wanted to play most. She spent two days obsessed with that game, the first time I've seen signs of a real "gamer" in my little girl. It kind of freaked me out to see her get frustrated and moody because she couldn't get very far in that game. (I tried it, too, and found that the touch-screen was inaccurate-- I would press to the right and Woody would go left, for instance.)
But then, after those two days, she actually won the game... and came to me, ecstatic. "I'm so proud of myself!" she said. "That was a really hard game!"
It made me see it in a different light. We all need challenges to beat, and this one turned out to be a positive one for her. Still, though, I wish there had been a third level-- "easy," "medium," and "difficult," maybe-- making the "easy" level actually easy. And I wish the touch screen were more accurate. It's close, but not quite, and that matters on the "On the Conveyer Belt" game.
My daughter loves that she can hear the characters' voices in parts of the games, and that the game congratulates her when she does well on the easy level and asks if she wants to move up to the difficult level.
I like that there really is an educational component to these games (counting, patterns, etc.) as well as entertainment.
