artifiical success/ video games/ life addiction

I think that the reason that video games work is that they stimulate the reward pathway somehow. If the reason why we get addicted to drugs is that they artificially release dopomine into the reward pathways then it is 'artificial success' - video games seem to have a parallel effect in that they set up tasks that you have to complete and then you have achieved success as well at a virtual task. Studies have been conducted that have found that the human brain is unable to distinguish between the social aspect of interacting and emotionally connected with television characters and interacting and emotionally connected with 'real' humans. So chemically, and in theory, a person could be totally emotionally and socially fulfilled if they never saw another human but watched every episode of 'lost' on repeat. So, it potentially stands to reason that if the brain can't tell the difference between virtual and real humans it probably can't tell the difference between virtual and real tasks so there should be no reason, chemically, why a virtual task would be any different than a real task. So they too are trying to get the 'artificial success' that drugs achieve but it actually creates a task that you have to get through in order to get the reward chemicals. Now, does that mean they are bad/addicting in the same way that drugs are? It seems like no or at least no more than life is bad/addicting in the sense that completing 'tasks'/'life levels' also stimulates reward pathways.
