How can playing games teach you about life

I think that games can affect some body's thinking. Sometimes games will have something such as killing people, but I think it might can let the kids know that we need to be good person, or else it will be similar like the games. And actually now there have many website is having many games that can teach people things, such as some games need to answered some question to go to the next level, this can make some kids play game and also know some new imformation, and this is also great for some students that can't accept for just a teacher speaking all the time. They might can use games to learned it. It's very useful.
