For example, both Final Fantasy XVI & STALKER 2 take up 152GB & 165GB on my 2TB external SSD. I mean, why are steam games HUGE as f*ck regarding their file sizes lately? Don’t even mention CoD (200GB?!), even with the fastest internet connection: you can’t bypass patience as these things take up time. For me, it took me about 2 days to finish (pause & resume download). I’ve finished installing KCD II (Royal Edition) and that was 85GB (took up 8-12 hours with fast internet, I was binge watching a TV show on Prime Video the entire time).
As others have said, it’s mostly audio and textures, with some of it being the choice of engine. Lossless CD quality audio and ultra high resolution textures and bump maps for a jillion triangle models take up a lot of space. The actual executables are relatively small, though certainly the layers and layers of frameworks that make up modern software development are somewhat to blame.
So it sounds like its an exchange of size for customizability.
If you had a different installer for each language and/or video quality, then each installation could be much smaller. But since we (gamers) want to be able to change texture quality “on the fly” via the settings menu, we have to deal with all the possible textures coming in the game files.
Does that sound like I have it right?
That is definitely part of it, but there’s also just plain more textures and models because people complain if they see the same texture or models reused a lot, and they want ever increasing visual quality. An uncompressed 256x256 RGBA texture takes 256 kilobytes to store. A 4k version takes 16 megabytes.
