I love video games myself, LOL! I played alot as a kid, although they were in an arcade since nobody had computers back then.
I sometimes wonder if video games can promote shorter attention spans and like ADD. I limit our guys to two hours on the weekend, total for the week. No more. If I let them, they would do it all day. They play this Lego Star Wars Game.
If it's rainy, they are forced to find something to do. It generally leads to imaginative play. If they could play video games then, they would, but we don't let them.
