"Call of Duty" marked the beginning of what would become an iconic and never-ending franchise in the video game industry. It set itself apart with a great World War II campaign that brought the brutal reality of war to life in a way that not many games managed to do so.

The game’s campaign was a standout for its length and difficulty, challenging players with missions that required strategic thinking and quick reflexes. Set across various European theaters of war, players experienced the visceral intensity of battle from the perspectives of American, British, and Soviet soldiers.

The difficulty of the game was a point of praise. It did not shy away from presenting a challenging experience. The satisfaction derived from completing tough missions contributed significantly to the game's replay value.

The launch of "Call of Duty" in 2003 laid the foundation for a franchise that would go on to explore various other eras and conflicts, but it in my eyes, this is THE Call of Duty. The one that stays true to its name.
