Even though I don't have time to emmerse myself in the world of video games, I am often intrigued by the theme of some games. Recently there have been many games relating to the end of the world, so naturally there would be many people being infected with viruses and having to fight for survival. This kind of world is almost always a popular theme. Yet nowadays there are too many problems in the world. The content of some games can possibly predict the future of the world. I only hope there would be superheroes to come and help us.
