Excerpt from this article:
My son and I do still play those competitive games, and I hope that he’s learning about practice and perseverance when we do. But those games are about stretching and challenging him to fit the mold of the game’s demands. When we play Minecraft together, the direction of his development, and thus our relationship, is reversed: He converts the world into expressions of his own fantasies and dreams. And by letting me enter and explore those dream worlds with him, I come to understand him in a way that the games from my childhood do not.
Touring the worlds that my son has settled over the last couple of years, I find a lot of the imagery one might expect from a kid his age. Throughout are standard fantasies like living in a treehouse or on a boat. The dominant themes vary as I pass through time: trains in his earliest worlds, then robots, a long streak of pyramids. Pirate ships, particularly half-sunken ones with treasure chests, remain a constant.
