I've always wondered.. Was a game like GTA5 80GB+ because it contained the audio for localized in-game speech for english/french/spanish/italian/etc.? Does this really happen? Aren't we at the point yet where the audio is only downloaded on demand for the localization of the PC unless opted-into later? Also. Don't need your textures for playing on an 8k monitor if I'm playing at 1440p.. unless I want them.
At least on Steam there is the _option_ for developers to publish individual depots for different locales, and a single game download can be made of multiple depots (so you could have a global base depot, and then put localised content in depots per locale). https://steamdb.info/sub/398272/depots/
