> The concept of physical vs psychological dependence is kind of outdated, see: https://www.youtube.com/watch?v=-EaiP31qWf0 https://www.youtube.com/watch?v=-EaiP31qWf0 You are conflating two terms here. Addiction (which is what the video is talking about here) is a set of behavioral patterns. I agree that the line between psychological and physiological in addiction is blurry. But addiction is not the same as dependence, which is about tolerance and withdrawal and is purely a physical phenomenon. To give some examples, when a person misses work because they are drunk or when they spend their rent money on heroin, that is addiction. When a person has seizures because they haven't had a drink in two days, that's dependence. I agree with GP, video games may be addictive but there is no physical dependence like there is with alcohol or, as you pointed out, even caffeine.
