I don't know if your question is serious or not. But it really can be an addiction, like gambling, or anything else. Delete the games from your computer and get rid of all credit cards with which your purchase the games. If you have an Xbox, or Playstation, get rid of them too.
It will be hard for a little bit but you will bounce back. Like any addiction, it takes time to break free of it - and you may find that something else replaces it - so watch for that--such as compulsive eating, shopping, hoarding etc.
