I wouldn't recommend avoiding computer games entirely, though. As a tool for training mental agility and flexibility, I don't think they can be beat. "Here's an entirely alien environment that operates on a whole different set of rules from anything you've encountered before... go!"
Forever kids have been making up their own imaginary worlds with different rules. They create it from scratch, they live it, they destroy it. Playing has been the world where many of us learned these skills and gained motor skills and sensory awareness all at the same time.
