What video game do you play the most? The practical advice differs based on what type of game it is.
For example, if your main problem is an MMORPG like World of Warcraft (as is usually the case), then there are various well-worn strategies to help you quit or cut down on your playing time. Whereas if your biggest problem is Call of Duty, Angry Birds, or online poker, those strategies won’t be as effective and a different approach will be needed.
