Horizon Forbidden West, whose DLC I recently completed is taking up 106GB on my system with the Burning Shores included. Final Fantasy VII Intergrade which I have owned for over a year takes up over 81GB, which is about the size of the newly released Diablo 4. I was actually surprised to find that Elden Ring only clocks in at 45GB.
I was thus quite surprised to discover that one of the most critically acclaimed games to come out recently was only taking up 16GB of space. Somehow, Nintendo has managed to take the newest Legend of Zelda game, give it the largest gameplay map yet (with multiple levels, no less), and still manage to implement one of the most innovative experiences with a file size that's not much more than the size of some game's saves. Certainly, the graphics do not have the texturing of other modern games, but the overall polish to the entire game is supposedly unmatched (I haven't played it yet, but what I've seen seems to agree with the hype).
To me, this is why Nintendo is one of the greatest game producers: they make high quality games that are fun to play, but that don't rely on massive power draws and file sizes.
