My opinion about video games:
Advantages: Leisure time, you get to relax and just forget about everything else in the world except that game. It also depends on it, because, they have games that you play that challenge your brain and sometimes even improve your skill.
Disadvantages: Sometimes, they can give us the wrong perspective on things and how to approach different situations. They also slowly rot human brains.
We mustn't forget this phrase: "Moderation is best"
If you use them in moderation they are good.
If you use them all the time… BE CAREFUL and try to make more narrow when you play with them!
I have the same opinion about violent movies.
