Call of Duty 4: Modern Warfare: What other Call of Duty game could it be? Of course, the first Modern Warfare would have to take the top spot during this conversation! This is the game that made headlines and brought casual fans into the mix - everyone and their grandmother heard about how incredible Modern Warfare is and were thoroughly convinced of that fact once they finally played it. The campaign may be short in comparison to other series entries, but it left a huge impression on everyone that experienced it. And the multiplayer? Damn near perfection! The introduction of UAV reconnaissance scans, airstrikes, and attack helicopters propped up the already strong gunplay and modes suite past entries introduced.
