What do you mean by "does not invite the player to explore ideas and concepts that are going within the game at the same time"? And why is this so important to a child's development that without it, "overall the child is no better off"?
I would say no to all of these, just like would say about TV. And it isn't that is important or not, it is just that it offers no fundamental difference from the media that has come before when it comes to development of the mind.
In real life, if you destroy or hurt someone else as a child, you are told that was bad and why. In extreme cases, you may be put on a time out, or forcefully removed from the situation. If you help other people, you make friends who will be more willing to help you.
So what is the fundamental differentiating factor, as far as emotional development goes, between minecraft and real life? Both have comparable consequences to a person's actions as it regards other people's feelings.
