My son requested I download Minecraft at some point in history; I'm not sure when. The months (years perhaps) of watching him engage the game impressed me. This game engages creativity in a deep and significant way, in ways no shooter one can. With his current creation, he's taking into account architectural details like work and room flow (currently building a bakery). Then when I mentioned to him about how Boeing camouflaged their Seattle plant during World War II (built a fake neighborhood above), he announced that he was building his own Boeing factory.
It delights me to see his brain working like this. And the standard gaming side-benefits (most noticeably better hand-eye coordination and dexterity) are nice, I love the creativity. His right brain is getting brilliantly stimulated. For that, I'm grateful.
