A sports game is a video game that simulates the practice of traditional sports. Most sports have been recreated with a game, including team sports, athletics and extreme sports. Some games emphasize actually playing the sport (such as the Madden NFL series), whilst others emphasize strategy and organization (such as Championship Manager). Some, such as Arch Rivals or 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 features the names and characteristics of real teams and players, and are updated annually to reflect real-world changes.
