First off, not to be insulting, but I think that's the funniest thing I've heard all day!
But really... ok, well, I'm no Dad (I'm only 21), but you could probably let him play star wars: Jedi Academy. That's coming out in about 20 days or less. There's really no gore at all, being a LucasArts game and it shouldn't be TOO hard, since all you have to do is hit the left mouse button and whirl the mouse around a bit to swing your light saber(s).
Another good game would be a flight sim. Maybe something like Crimsons Skies. I really liked that one myself. NO GORE whatsoever, and not many people even die. They just eject. You're supposed to be in some parallel universe-type era, set in the 1920's, where there are air pirates, who hunt down zepplins and steal their cargo. There's a really engaging story line to it as well, so I'd definitely pick that one up if he doesn't like the games purely for their "shoot-em-up" factor.
Any sort of World War game or real-life situation type thing (IL Sturmovik, Counter-Strike) or even a fantasy FPS like Unreal Tournament 2003 maybe a little too violent for his age.
If he's anything like my girlfriend's little brother, Eddy (age 10), and likes building things and managing their progres, the SimCity series might be a winner. SimCity 2000 might be good since it's not too complicated. The later ones have A LOT of micro management and might be too hard for him to figure out. Roller Coaster tycoon is another one of Eddy's favorites.
There's really a plethora of good, non-violent, yet extremely fun games to play out there. Head over to your local Electronic's Boutique and ask the guy who works there. I'm sure he'll be able to help you out.
