Personally, I don't need to be told not to play for too long because I will have no much spare time to get more gaming time. So, it's only when I get to finish my daily work, then I will play games.My current approach is to limit the gaming time. And make sure that I am spending not more than 2 hours. This way I make sure to only spend time when I don't get burn out. This is my approach and that seems to be working for me. I may consider addiction if I tend to look at the phone every 2 minutes and spend time there.
