As you know gaming makes life of a lot of people happier nowadays. But I should point out pros and cons of gaming.
You might consider gaming as a type of entertainment. Lots of people spend their free time driving, flying, killing, creating and what not escaping the reality. Games can be educational, funny, they can teach skills such as strategic thinking, interpretative analysis and problem solving.
However, gaming can be very addictive and make children become accustomed to violence. Furthermore, as you can see around you video games have negative effects on children and distract them from school homework and doing sports.
To sum up, it is up to you to decide whether you play video games or not, if you want to use gaming as a kind of entertainment or to avoid danger of it. Choose what you love, as to me I devote my free time to education, sport, family and friends.
