I think that usually a guy which play games for a long time, risk to became a gambler addicted. Which method you use for stop plaiyng when you understand that you are near to became addicted?
For example, i don't play a lot or for long time (i play games spot during my free time), so i have no idea about, but i trade forex all day and when i had a significant loss i usually turn off my Pc and i go out for a drink , just for not run behind loss.
It is easy to spot a person who is addicted to gambling like you can see him everyday in the gambling place and who can't control himself to play even how much debts he has already.They don't mind how much money they had lose everytime they gamble ,they think that they can get more profit on it.
