Look man. There is no way I'm going to debate such a complex issue on a damn destiny forum but take a look at some of those gjallarhorn videos where it shows grown ass men acting like they won the lottery. That is a reaction totally out of line with what a person who doesn't participate in Destiny would consider normal. It's why the videos were so funny because they were absurd. You are looking at a huge endorphin rush to that persons brain. The same endorphins that are released when u do all those drugs that people are "allowed" to be addicted to. Your body doesn't have different sets of endorphins for situations. It's one size fits all and if the external stimulii are appropriate, they will be released. These endorphins cause the "high". These "highs" are what we chase. It's why Destiny can be addicting for some people. Probably a small percentage but it shouldn't be trivialized. You think it's only an addiction if it's associated with physical symptoms. This isn't true.
