Fortnite versus Call of Duty is the defining rivalry in modern gaming — two franchises that have dominated the shooter genre for different reasons and with very different audiences. Fortnite revolutionised the battle royale genre with its building mechanics, created the live service game model that the entire industry has copied, and built a cultural phenomenon that crossed into music, fashion, and film. Call of Duty is the best-selling video game franchise in history — a military shooter of brutal simplicity and addictive progression that has defined online multiplayer gaming for 20 years. Fortnite attracts a younger, more casual audience. Call of Duty retains the hardcore competitive gamer. Both are free to play. Both have hundreds of millions of players. Which is actually better?
