Oh, I think we just have different definitions of "foley". And maybe anolog and digital too, but whatever. I'm in school for sound design, so I'm totally showing my bias here - but there's a lot more art to it than just using something other than a Colt 1911 for a Colt 1911 sound. That generally doesn't happen any more, sure, but there's still a lot of art and skill involved in sound design. You might be able to pull a bunch of gunshot sounds from a library (and someone had to go through the trouble of recording all of those sounds, which is an art in itself), but then you've got to edit the sound effect to sound right in whatever space it's coming from (outside, in a huge cave, in a tiny apartment, in the tiny apartment upstairs) - for games they have to set up acoustic spaces to do this dynamically instead of baking it into the audio files.

And there's still a ton of creativity involved in beefing up some of those stock sounds, like using bent scrap metal to enhance some of the gunshot sounds, or basically making any sound effects for any of the fantastical wasteland creatures. https://youtu.be/Lr5olzm9jXg?t=34m20s.
