I know almost everyone has said this, but: Great Article!
My little brother (9 years old, diagnosed autistic at the age of 1) and I try working his social skills by cooperating in Little Big Planet, sharing time with him is always a new adventure, and we both learn things from each-other. He still struggles with putting words to express what he feels and thinks, though he is a great listener and understands a great deal of what is being said.
When I hear people talking about the negative consequences of gaming I feel that we all should put things in perspective and see both sides of the argument. Seeing how video-games represent a great help to autistic kids (and to other people too) I feel proud of being a gamer.
