I'm not talking about addiction - I'm talking about filling up a person's time because they have all this free time and if not filled, they have to deal with reality and/or hard choices. They choose to quickly fill the time up, so they don't have to do (and deal) with anything else besides said activity, eat and sleep.

It doesn't have to be gaming - it can be Reddit, Facebook, Drinking, etc.

(It's also different than, say, a new game is released and we all go on a 3 day gaming binge. Work/Career/Paying Rent/Job >>>> Leisure Activities. Prioritizing.)
