But you can't compare lego and playing Wii tennis, one is a competitive game, the other is coop. Imagine kids outside playing some competitive kids games and playing Wii, that is more fair comparison. Both will induce similar behavior in kids, at least mine: sometimes getting angry or crying if they're not the best, taking a ball and not wanting to share with others, etc. At some age all kids do that and then they slowly learn to control it better. Of course, going outside and playing with other kids is the best, but sometimes they can't do it and then I see Wii as much better substitute than classic video games or lego or whatever (don't get me wrong, legos are great, just not for the same reasons)
