The player can start playing after about 18 GBs are installed. Depending on network speeds, the install time can vary greatly. The game will continue to download and install as the player is playing.
If the user ever wants to switch speech languages from the one installed and original installation, which is based on their system language setting, they can change it in the Main menu. At which point an additional language pack must be downloaded and installed. The player does not need to reboot the application in order for the new language to work, but they will have to wait until the language pack is fully downloaded. An installation screen will appear with a time estimate if the player attempts to load into game while the language pack is downloading.
