When the question of money in video games influences clinical practice in addiction treatment

Video game playing is constantly evolving. The expansion of Internet has allowed gamers to exchange and compete with others players around the world. Internet has also brought the possibility of complex financial transactions concerning video games. This paper suggests addressing the main types of financial expenses involved in video game playing: gaming equipment, video games, subscriptions, downloadable content, free-to-play, e-sport, crowdfunding and the shadow economy. We address the close relationship between gaming and gambling, including through the scientific literature. Research has been conducted to investigate this relationship for a long time but payment modes in video games have recently changed dramatically. The luck in video game expenses is becoming increasingly more important. It therefore seems relevant to consider the impact of the link between gambling and gaming in clinical practice of addiction treatment. Clinical cases drawn from a center of addiction have been selected to illustrate our reasoning. Clinical research on addiction is still in its infancy when it involves the association between gaming and gambling. The legislation around these practices must also progress.
