Most of my kids play Minecraft. I’ll share our experience and our rules.
The following kids play: Age 14, 11, 10, 8, 7, 5, 4. They play using Kindle Fires, not online, though they can use a local network to play together with each other in the house. They play for an hour each afternoon while my 4 year old is on the toilet for his daily enema (that would be Mason, he has Spina Bifida and neurogenic bowels among other things). That’s it. No playing other times. (We have enough Kindle Fires for them all to play at the same time).
Our rules:
1. Don’t whine about wanting to play or you lose the next day’s turn.
2. Don’t kill gratuitously. Yes, kill for food or defend your home/villagers. But don’t just spend a day going around killing for fun. Because it’s not fun.
3. What is fun? Building, creating, and crafting worlds. They do this with skill far beyond what I could have imagined 6 months or a year ago when they first were introduced to Minecraft. For example one son is making a replica of a castle right now while a daughter created the Tardis (inside and out) from Doctor Who and a son has created a pyramid and world to go with our ancient Egypt study. Others are farming and raising animals, building armor and outfitting armies for mock battles they’ve read about, etc.
I say each family needs to do what is right for them. So if that is no Minecraft, great. If it is some Minecraft, great. Just find what works for you.
