It definitely is an interesting read, if a bit short for my tastes. I definitely think it was a smart idea to keep the option of it possibly connecting to violence open at the end.
Personally I feel that video games CAN contribute towards violence, however it is only a very minor contribution and only with in a select group. Many people are just fine with it and that is a great thing, but those who are too young to understand video game concepts and have poor parenting have a chance of being affected in such a manor.
Still, as I said, it was an interesting read.
