Size has become something of an issue with quite a few games because they're often... Annoyingly dense in size. Titanfall comes to mind with 35GB of uncompressed audio.
Call of Duty: Legacy Edition has been found out to be a total of 130GB. That includes both the base game and Modern Warfare remastered.
Oh and Voodoo Vince RETURNS.
