Minecraft becomes publishing sensation

Like millions of parents, Aaron Sacharow welcomes those moments when his son - 7-year-old Tyler - takes a break from video games and picks up a book instead.

He will even settle for the book being a guide to Minecraft, a game that's sold more than 50 million copies since it was originally released in 2011.

"I don't want to say it tricks them into reading," says Sacharow, an IT project manager based in Miramar, Florida. "But there are books kids are reading for schools and books that they hopefully like in their free time. And if Minecraft books are a motivation to read, that's a good thing, right?"
