Consequces of online gaming

In American English, "gaming" means "gambling." Is that what you intended to say?

With a couple of rare exceptions (such as a professional poker player in a game with amateurs), all gambling has the same consequence. The gambler loses money in the long run, because the odds are in favor of the house.

The problem with online gambling is that it allows people to spend more time gambling. They don't need to drive to the nearest Indian casino or wait for the next visit by the neighborhood bookie.

Therefore, the consequence of online gambling is that the players will become poorer, faster.

(If you are referring to online role-playing games, that is a different subject. Their biggest consequence is that young people devote too much energy to "virtual adventure" and "virtual socialization." They develop complex fantasy personalities for their online avatars and learn how to cope with the challenges of the game's universe. They are in danger of growing up with poor social skills and limited ability to cope with the challenges of the real world.)
