According to Activision's post on X (formerly Twitter), the huge file size is due to the increased amount of content available Day 1,  which includes map files for Call of Duty: Warzone, support for Modern Warfare II items, and the new open-world Zombies mode.

This is the case for Call of Duty: Black Ops Cold War as well. The entire game takes a whopping 125 GB on a person's hard drive, which is simply ridiculous since developers should be responsible for optimizing their games on PC.

Beginning September 18, 2024, a Nintendo Switch Online membership is required to participate in co-op and competitive online features for many first- and third-party Nintendo Switch games, including Splatoon 2, Mario Kart 8 Deluxe, ARMS, and Super Smash Bros. Ultimate.

Other free-to-play games like Rocket League can be played without a paid Switch membership. Nintendo Online is only needed for multiplayer over the internet, however.
