I have no idea how limited the options are, but this happens with every rendering software, people just slap models/assets they find in the same places and you end up finding the same faces, body types, clothes, hairstyles, etc. copy pasted everywhere.
the only one that comes to mind with some elements of this is Alexia's return or Tara's liberation, and it's only a couple scenes out of the game as a whole
even more important than the amount of content is the quality, it's very easy to just add random scenes with throwaway characters that don't show up again just for filler
