^ Adoption! Even easier is adopting from a visibly different ethnicity so they'd likely just figure out on their own they're adopted! That's my plan!!!
But seriously. I enjoy the heck out of it, so why not? And I do think it has its benefits (I hated reading as a kid, games encouraged me to do so...well, y'know, back when games didn't just read all the dialogue to you). Perhaps just having it in the house will pique the kid's interest, and there are far worse hobbies to take up (I'd still encourage other activities as well, reading or playing an instrument). I've always found games as pleasant time wasters, the things that aleviate every having to start a conversation with "I'm booored".
