That made me think! Wii Sports and Wii Fit are both non-fighting. Not EXACTLY educational, but not horrible. There are some snowboarding games. There's Endless Ocean (think that's the name), but I don't know how interesting it is.

For what it's worth, pretty much EVERY boy I know loves Wii Lego Star Wars, including my two (5.8 & 3.2), but it does have fighting and isn't educational.

We just don't let them play if they are getting addicted to it. We tell them if it's becoming that important to them they need a break since it is just a game and not that important in the grand scheme of things. It makes them annoyed and pissy for a bit, but then they get over it.
