The police chases were expanded to become much more varied, and they were infused into the central campaign of the game where players were tasked to challenge 15 Blacklist races in one-on-one competition. The gameplay focus of NFS: Most Wanted was shifted from challenging rival gangs like in Underground games to larger in scope and more in-depth races against the police force. Streamlining the driving systems, car customization and mission progression and overhauling the gameplay systems of police chases, free-roam aspects of gameplay and introduction of multiplayer modes, Need for Speed: Most Wanted very quickly became one of the biggest critical hits of the entire franchise, and with time, the best-selling Need for Speed game with over 16 million copies sold. Need for Speed Most Wanted is represented the culmination of the efforts of Electronic Arts and the developers at EA Canada to create an open-world racer that would satisfy millions of fans of NFS games that were in the early 2000s enjoy the games such as Hot Pursuit 2 (2002), Underground (2003) and Underground 2 (2004).
