I have a 8 year old friend who I began teaching when he was about 6. I only had a PS2 at the time, so I was just going through all my games with him. I don't own a lot of violent games, and I stayed (and still do) well away from all the finicky RPGs.
I'd suggest what a lot of other people have: Jak & Daxter, Ratchet & Clank, Crash Bandicoot, any fighting game (that doesn't have excessive amounts of blood in it) and simple enough action/adventure style games. Though, I learnt to play games with Kingdom Hearts when I was 6-7, so I suppose it doesn't matter. He's gonna develop his own tastes re game genres, anyway. Try him out on all different ones.
