目前还是有些人喜欢购买游戏实体版，因为拥有光盘就可以在不下载大堆数据的情况下玩游戏。但是《使命召唤19：现代战争2》的光盘似乎并非如此，其PS5版光盘中只有70MB的数据，可能是某种激活密钥和DRM。
当你试图在不下载任何东西的情况下运行光盘，会提示玩家连接到PlayStation网络，下载一个允许他们游玩的更新，这使得购买光盘变得毫无意义，目前不知道Xbox版光盘是否也是这样。
The PS5 version of Call of Duty: Modern Warfare 2 only has around 70MB of data on its physical disc, rather than the more substantial number of files one would expect from a major game release. According to MP1st, players who managed to get their hands on physical copies of Call of Duty: Modern Warfare 2 discovered that the discs only contain 70MB of data, which would likely be some sort of activation key and DRM. Presumably, inserting the disc into a PS5 wouldn’t do much besides prompting the console to download the entirety of the game. Trying to run the disc without downloading anything prompts the player to connect to PlayStation Network to download an update that would allow them to play. It is also worth noting that players saw a 40GB day one update before they could start playing. Shortly after its day one patch, the total size for Call of Duty: Modern Warfare 2 has grown quite a bit. According to reports, it is now sitting at around 152GB of data. While there has been no confirmation about whether the Xbox version of the game shares this detail, it would be quite likely that Xbox discs would also similarly include just the license data, rather than a full game that can be played without having to connect to the Internet.
