this is unfortunately why a lot of games are intentionally bloated to give the illusion of having more content when it is really just bloated by lack of compression and using wasteful formats that create larger than needed sizes with no real noticeable gain in quality.
Lack of compression, and also added dialogue, and extra needless images that add nothing to the story, or quality of the game...yes. lol
A game that is 15gb, that easily could have been 2-4gb, and the person compressing the game is always like "I can't compress it anymore." But, other games of the same type, same length, are down to 2-5gb, uncompressed, and have a compressed version under 1gb.
