Video games and virtual worlds are emerging forms of digital media and entertainment. Studies show that while video games are often seen as violent and isolating, they can also have cognitive, attitudinal, emotional, and physiological effects on players. However, games like Wii have shown potential benefits by being family friendly and encouraging physical activity and social interaction between players. As these media continue to evolve, more research is needed to understand both their impacts and future applications, including how virtual reality may further blur the lines between games and real life.
