Why multiplayer games cause more stress in people's especially clash of clan ( based on my own search and other people view point's)

Today i am talking about the most popular multiplayer game clash of clan coc. My little brother and mostly boys of my family additict to it as i can say that when i see them they always seen playing coc.
Coc is a multiplayer strategy game created by supercell as i know it is very addictive.
It has some positive and negative points like other things.
1_ it enchance your ideas
2_it make you more stragic
3_your leadership power is also check that how will you preform and how will you take responsibilities.
4_ also help you how can you cope your problems.
And now some negative points
1_ it make you aggressive
2_your children become mostly angery all day
3_ they only think talk about coc especially if they are leader.
4_they may use your money without permission to get gems ( it may become cause of trouble in future).
But all these games are not trouble casting
Another app of supercell hayday is a best game . it will help you to restore your peace. The graphics of hayday is best it help you to reduce your anxiety.
And also help you to learn about village life.
But it also had disadvantage over all this app is good .we can not say what is good and what is bad for some one one things is bad and one thing is good . but we have to love everything's.
( if you like my artical then like my page and if i can say anything bad because it depend on my observation then sorry . i think you forgive me if i can say any thing bad.)
