Ever since the original Modern Warfare was introduced to the world in 2007, Call of Duty became a yearly juggernaut in the realm of first-person shooters and online multiplayer. Most games in the franchise, especially during the series’ “golden age” that started with Call of Duty 4: Modern Warfare and arguably ended with the first Black Ops, have acquired an impressive player base that helped Call of Duty become one of the most financially successful video game series in the industry. Nowadays, Call of Duty games released in the late 2000s and early 2010s tend to be even more beloved by fans than ever.
