Says Leala and Kenny... who DON'T HAVE KIDS! lol
Seriously though, it is all up to the parents to gauge what the kid is into, and what the kid wants out of playing... WoW or any other game. I don't feel that Haf, me, the listener who wrote the e-mail, or any other parent, should be judged or belittled if they are letting their kids play games, and determining what they what their kid to get out of the game.
Last night I played WoW with my son and all he wanted to do was help the neighbor girl in the level 1 starting area. Fine, let's run around in circles killing plainstriders. I am down for what he wants to do. But, when it comes time to do quests, he knows how to assist, loot, and be responsible with chat. In general, I am teaching my kid how NOT to be a dumbass. That is what he wants out of the game, and that's what I want to teach him. And I would get that much out of fucking Club Penguin or Free Realms, or whatever else we would play together.
Go squeeze out a kid. I bet your views would be different. They don't come with a manual on how to do things... you have to figure it out for yourself. Haf and I grasp onto EVERYTHING that interests our son and use it as a teaching tool. "You like reading Captain Underpants because it is funny? HERE, I will buy you the entire fucking series!"... "Yes, Lego Star Wars is awesome, and you are great at it! If you save up money you can get Lego Batman and Lego Indiana Jones!"... Every occasion holds varied opportunities for teaching life lessons. If it happens to be in a video game, fucking kill me for trying.
