If it results in it growing up, he spends the game more and more time and become a champion - this is good. If the results do not grow, but it plays a bit of time for relaxation or excitement, it is also good. If the results do not grow, but he spends more and more time on this game - it's bad. Just bad if the results do not grow, but it seems that growing up, and the player once again spending more and more time. It makes no sense to waste time on empty. Consider the beneficial and harmful habits, such as sports and drinking. The increase in time and (or) increase results in the first case - it is a success, and in the second - a failure. That is, if you exercise regularly and your physical results are growing - it's good. It is also good if you are more often than before (but in moderation), doing sports. But if you're used to drink a glass of vodka per month, and now a couple of glasses a week - this is not good, it is - not a success, it is - a step towards alcoholism, a step to the big problems of life.
