Online Game - Good ? Bad ??

Online games have various positive points as well as negative points. Different people have different views on this topic. Here are just a few of my observation that I feel quite alarming.

• 7.30 in the morning .It was the first period . Before lesson started, Jack has already fallen into a deep sleep ! No matter how hard the Cikgu tried to wake him up , he still slept like a log.You might think that he was sick or why was he so tired ? The rest of the students laughed & advised not to wake him up. It seemed he slept 2 hours this morning as he played online game throughout the night ! What ?! Well, he was really over-exhausted & it was impossible to wake him up!
  
• 6 something in the morning , the school authority caught students enjoying their game at the cybercafe.Can you imagine some of these students were from the afternoon session .Since what time they were there ? Didn't the parents know their children's whereabouts ??
  
• San's favourite online game is DOTA which he plays day and night.Sometimes he is absent. Guess you know where he goes.During lesson he just ignores the lesson and talks non-stop about his adventure & achievement . Some of his friends are fascinated by his sharing & join the game as well. Others just can't stand him telling the game all the time.
  

These examples show how serious the students indulged in the game.So much so they have lost their self-control. For the weak ones, they have already given up in their studies. But how about those from good classes. I've seen the same scenario, and their studies are deteriorating !

How do you see this issue ?
