Destiny 2 took up about 30GB of space at launch, but after so many updates, patches, and expansions, it hit 120GB on PS4. This isn't specific to Call of Duty, either. Those things all take up space, and constantly adding more will obviously cause the game's size to balloon over the course of a few years. Season two of Black Ops Cold War recently launched with similar additions. And more just keeps coming: season six of Modern Warfare added another round of new maps, operators, weapons, skins, finishing moves, and game modes, just like many of the previous patches. Even if it seems like the game has less to do than an open-world sprawl like Assassin's Creed Valhalla, it could have a huge amount of large, unique assets, which can drastically increase the space taken up on your hard drive.

Remember that on top of graphical advancements, long-running multiplayer games like this are designed to keep you coming back over and over again-especially those with free-to-play business models like Call of Duty Warzone. When asked in March about why the game was so big, production director Paul Haile himself claimed there's ' just a ton of content,' and there's certainly some truth to this. A year after Modern Warfare launched, though, the game had inflated to 200GB, more than three times its original size.
