Regarding this reoccuring theme, which is addiction will return if the void is not filled, I gotta add a Bible verse, which paints the same lesson with a more graphical and figurative illustration:
"When an unclean spirit goes out of a man, he goes through dry places, seeking rest; and finding none, he says, 'I will return to my house from which I came.' And when he comes, he finds it swept and put in order. Then he goes and takes with him seven other spirits more wicked than himself, and they enter and dwell there; and the last state of that man is worse than the first." (Luke 11:24-26)
This seems to apply here too, whether you are talking about chemical addiction or video game addiction.
