This was a great introduction to understanding what the hell my 9 year old was talking about. Withers, endermen, potions, spawning, et cetera. I have felt comfortable, after reading this book, playing alongside my son as he spawns dogs, kills zombies, and attacks villagers. I'm sold on the school of thought that while video-gaming and technology can be isolating, it can also be a key to unlocking imagination. Minecraft, to me, seems like digital legos. I would play with legos for 4 or 5 hours at a time and then clean them up. Minecraft doesn't have the cleanup, but does spark creativity. I am more comfortable letting him spend two or three hours on Minecraft knowing that I can drop in on his world, or carry on a conversation about what he's doing in Minecraft. I found this book accessible and mostly helpful. I am not one for digital copies of texts I'll refer back to, but the price on this book as a digital text I can easily tab through on iBooks made the purchase a no brainer. I'm glad I can at least talk to my son now about his all-consuming passion with at least some knowledge.
