Loved to read your post. Even I don't play Minecraft I can see my kids getting excited about playing it. You are right it is inclusive (there is even an Esperanto version (http/www.youtube.com/watch?v=Y6jjQQvwtlo). And Minecraft doesn't need all the other bad stuff like violence... indeed is a more creative version of LEGO. However there is one real difference, Minecraft is only on the screen and not really in your hands. And it seems harder to know when to stop playing. As you said: Don't forget to sleep.
