That's just the thing...implying "addiction" for anybody who has ever done a loot run is a totally ludicrous statement. Can your mind only work in such dichotomies? I mean really, you seem to me from your statements to think people either loot run and are "addicts" or play the game in a self moderating manner and are therefore "healthy" and "reasonable".
No matter how you try to justify or spin it, comparing people who loot run (who are everybody from casual players who do it if they only have an hour to spare to people who do it 60 times in one night, every night they can, so the gamut is wide indeed) in a video game meant for entertainment to people who use drugs that damage mind and body and are used for much more the recreation is absolutely the most ridiculous, unbalanced and irresponsible thing I've heard.
You seriously need to re-evaluate your analogies, bud.
