The game is excellent for schoolchildren and for children. Many say that playing games is bad for children. But I think that playing games is harmful only if the playing time is too large and the game does not occur during the lesson.
You can control the playing time with a timer. But to control that children do not play during the lesson is necessary in this way - children must first complete the lessons, they should read a book or at least an example of an essay about gun control or another essay from the site https://samples.edusson.com/gun-control/ and then play.
Finally, I want to say that the game is exciting and therefore, when playing this game, people have to control the playing time.
