Gaming Addiction is pretty much brand new thing that I think is built on a bit of junk science, as it's something that you can't really group in the same addiction group as things like Alcohol addiction, or drug addiction. In fact I think it would be more similiar to gambling addiction.
The reason I say this is simple, just because someone spends X amount of time on a game a day doesn't mean they are addicted. We don't really talk about people being addicted to TV despite people spending hours watching it.
It's more similar to Gambling addiction as you can have two people who gamble for the same amount of time, and only one of them may become addicted to it. In fact lotto machines often use the same tactics as mobile games use to get people to keep playing.
Talking about the How to help yourself section of the post, I don't mean to sound blunt but the likely hood of someone with addiction helping themselves isn't very high. Most people don't even realise they are addicted to something and usually need a kick from someone else to get on the path to help.
For instance someone who is addicted to video games, truly addicted, are going to forgo things like exercising to play games, and they may set time limits but chances are they wont follow it. It's like a gambling addict walking into a casino with the mind set of only spending $20.00
