I’m aware. Most large studios don’t use sound libraries (outside of iconic sounds as reference, like your example) because they want ownership of the product and they have teams they pay to record and master the sounds. Bethesda is headquartered in Rockville Maryland. There are many places in the area to get crowd sound effects recorded. Hell, they could even just record an office event or something without going anywhere. It’d be odd for them to use a crowd sound effect directly from a sound library.
