Addiction to both gaming and gambling as almost like the same, it's like a two broad roads from different directions that lead to the same destination, that is, addiction to gaming and gambling both destroys the mind/brain, and causes the collateral damage which is the loss of money that should have been used for other important things in the victim's life.
Agreed, addiction in gambling or gaming are all the same because you'll be losing money in both of them. An individual that spends money gaming is going to have the same side effects as someone that's always gambling. While the gamer is looking for satisfactory for his desires in playing the game, the gambling is looking for money from the bets he takes.
Victims in both situations can get disoriented from being addicted to what they're doing and that gives ways for other disadvantages to come because gambling addiction doesn't come along, after noticing you're addicted to something, you can start noticing other bad characters that you'll begin to develop too without plans for them. You'll be less discipline with your money and begin to have poor habits towards money because you're not using it correctly.
