I am playing game since 6 year until 25 year right now, and it make me more senior than you,hahahaha. There nothing wrong if you keep playing game, as long as you don't waste most of your time only for game. My advice is play for 3 hour per day or playing when you don't have any activities. But if your friend ask you out, choice them rather than playing game. The point is decrease your gaming activities and make sure use your time to do more productive activities.
