The cons far outweigh the pros. Gaming addiction is absolutely horrible. My father's friend used to be proud of his son. My father told me to look up to him growing up. Top of his class, aced every high school subject, admitted to Bejing University med school, athletic as well. Once he left home to attend medical college, his sudden freedom allowed him to go about his gaming unchecked. He spent all his money, borrowed more from all family friends for internet gaming. He failed all his classes. His father spent all his free time going from internet cafe to internet cafe looking for him, spent several tens of thousands in RMB buying presents for his professors and program director to give him a second chance. They did, and he failed everything again. His former athleticism in track has been replaced with a somewhat hunched back from sitting in front of the computer gaming in a slumped position. Playing Call of Duty does not make you a soldier, not even a little.
