As you may know, cross-play in gaming has been an enormous success and has also been very beneficial. You see it a lot in major multiplayer games such as Fortnite, Apex Legends, Call of Duty, etc. It is excellent that you can play with friends from other platforms. You will be happy to know that the upcoming Battlefield 2042 will also have cross-platform. That is undoubtedly something for you to be excited about.
However, there is a catch to this. The cross-platform functionality is only available to current-gen users. PlayStation 5 and Xbox Series X and S owners will benefit from this. The last users will be separated due to the versions having different match sizes. It is understandable that your final-gen users might be upset by this, but with the quality of the game, it might not be a big problem anymore.
