Since she was really little, my eldest cousin has been fascinated by WoW. Whenever she came over, she would watch me play. I would dutifully run around, maybe do some dailies or professions, and she would be absolutely spellbound. I couldn't wait until she was old enough to play with me.
Recently, she turned 11. She had progressed to leveling a character on my account, a hunter, and was surprisingly adept considering I flaked on turning on newbie hints. So I bought the games for her and started lobbying my aunt and uncle to let her play with me. Her parents were understandably concerned about online safety. They aren't familiar with WoW except through me, and there are a lot of safety issues with letting your kid play an interactive game online -- not to mention the $15 monthly fee!
