Debuting all the way back in 2003, the Call of Duty franchise has only continued to grow more popular with each new entry, and while its recent sales may have dipped slightly due to very valid criticisms, those sales are still monumentally high when compared to the vast majority of other modern-day releases. That being said, while hundreds of thousands of players are still logging into Call of Duty: Warzone and the most recent Modern Warfare games, many fans long for a return to the golden age of Call of Duty, which often sees them boot up some classic entries.
