The actual dolls find their place to the doll shelf and stay there. The Web game, on the other hand, seems to be very appealing and interesting. My daughter is 8 years old and she loves it. I see a few benefits:
1) She's happy (that's the main thing, isn't it?)
2) She practices her English (We live in Israel so it's important)
3) She takes responsibility. She actually works to keep her pets happy.
4) she is constantly improving her computer skills.
I think its all good.
