Minecraft is a video game that has a lot to offer. At its core, it's very open-ended. If you want to have an adventure, you can have an adventure. If you want to build something, you can build something. If you want to talk to your friends, you can talk to your friends. If you want to kill monsters, you can kill monsters. So the game appeals to a lot of people. It makes a lot of sense to take a game that is already fun, that is proven to be enjoyable to kids, and try to find a way to bring it into the classroom.
