Computer games are addictive. That is the main reason children play them for hours on end. There are several disadvantages to spending a lot of time in front of the computer. Computer games merely provide entertainment. Children who are addicted to computer games tend to have poor grades because they do not get enough time to focus on their studies. Also, they have reduced social skills. They are constantly glued to their screens and show hardly any interest in interacting with their family members or peers. This can lead to social isolation and serious behavioural problems. Some popular computer games glorify violence and crime. Children who grow up playing these games may get into anti-social activities.
