i never get the argument about time spent on games
one person may play golf 30 hrs a week
one person may paint 30 hrs a week
one person my masturbate 30 hrs a week
who is right/wrong ? none of them are . everything is just a passing of time. its just what you choose to do with your time.everything else is irrelevant .
if you choose to spend time elsewhere that is your choice. others choose differently are exactly the same as you just doing differently with their time.
500 hrs is crazy on a game but as said some people will do other things for just as long or more.
