All kids are different in their susceptability to this obsession. For a year or two, around ages 5-7 we battled this addiction. Had to buy the new game, obsessed with playing, wouldn't do anything else. Now at 8 I can't even interest him in a game! I will say that I sometimes limited play or took it away but I was not very consistent and in the end I let him choose his own limits. It was actually when that happened that he reached saturation level and grew bored with the games. We have Wii, Playstation and DS and they are all three sitting alone. :-) I never thought that day would come. He does enjoy some computer games now like Civ. IV and Disney's Pirates of the Caribbean but has no trouble turning them off to go do something else. Hope this eases some frustrated parents...
