A sports video game is a video game that simulates the practice of sports. Most sports have been recreated with video games, including team sports, track and field, extreme sports, and combat sports. Some games emphasize playing the sport, whilst others emphasize strategy and sport management. Some, such as Need for Speed, Arch Rivals and Punch-Out!!, satirize the sport for comic effect. This genre has been popular throughout the history of video games and is competitive, just like real-world sports. A number of game series feature the names and characteristics of real teams and players, and are updated annually to reflect real-world changes. The sports genre is one of the oldest genres in gaming history.
