The most popular type of entertainment in my country is playing video games. Because they satisfy our needs for achievement and recognition. Video games also keep us interested with puzzles and mini-games, and engaged due to their attention to detail. They transport us to new realities and put people's dreams on screen. And, of course, sometimes people can make money from gaming. It helps children to be more independent financially from their parents.
