An actual video game addiction is rare, an addiction is life and behavior altering. I would say the most video game addicts we had were at the good old World of Warcraft times, when people played for 14 hours a day, 7 days a week. I was there i know what i am talking about.
With gambling it is different, and it is a downward spiral, you will always have that litle voice in your back head that tells you, "Come try again, you already spend so much and didn't win yet, just another 50$ , you will win this time for sure" and hen you dont win and spend another 100$ because you must win.
Also here is exactly what NC's strategy is with this game, you can believe me or not i don't care.
-Create artificial scarcity of ingame resources (e.g. hongmoon jewel powders)
-Inflate the market to drive gold prices up (e.g. Hongsil treasure hunt)
-Suddenly provide a huge amount of scarce resources for a limited time for real money.
-Profit.
It is very transparent and you all fall for it, and worse people like @Grimoir keep defending this practice.
They are now so far in creating artificial scarcity that you can't even get stuff from events,see they reduced the amount of event curency so you can't buy pet pots/oil for them, and just a short time later flood the Shop with exactly those.
