Games for kids

One of my good friends asked me to recommend some PC games for his 8 year old granddaughter (she's a Birthday in a few days).
For a moment I thought of Counter Strike (for dickz), but not sure that my friend will remain being my friend after that
The other thoughts were Harry Potter, Folklore (if it wasn't a PS3 exclusive).
If you were in my place which games would you recommend? His daughter's PC is new, but cheap and not really fast. Thank you.
