"We make games so that people can enjoy them, and I've noticed that throwing around a dirty word like “addiction” is a lot like throwing rocks at people. Heavy rocks.

Yes, this makes bored journalists and unpopular politicians very happy. China has already thrown a fair bit of legislation at video games, whether or not games are the problem. On the other hand, such legislation might fail to address the real problem. In this article I explain addiction simply. Then, I talk about research that attempts to connect addiction to gaming, and some clear problems in that research. One caveat: this article is not going to make anyone into a trained clinician."
