I'd be really curious to find out what the history of those oft-used EQ sounds are; whether or not Verant bought up a library when making the game, or if they decided to take advantage of non-exclusive licensing after the game took off.
Those elements are
everywhere, and they're spread out across all kinds of libraries. I know I've worked on an animated project before where the music supervisor licensed a "spooky elements" library that had, among many other sounds, a bunch of skeleton crunch/collapse samples and the skeleton giggle that were identical to the EQ elements.
Also, fun fact - a lot of musicians are hardcore gamers (the fuck else do you do with 10 hours of drive time a day), as are a lot of producers/engineers, and they get a huge kick of sneaking samples/elements from games or movies into songs. Take a listen to this track -

Listen carefully and in the background of the chorus you'll hear a clip of the abjuration spell cast.
I picked this one, not because it's done well but because it's more obvious than most. I personally would have pitch shifted it up so it wasn't rubbing against the track so bad, but whatever.
Kinda related, I've been trying to place this one for a while and I think it's a Toyota Camry open-door sound shifted to G (spoiler alert, it's a Kelly Clarkson track):

If any more examples of EQ/game samples hidden in tracks come to mind, I'll post 'em.
