Well you say something quick and easy why not implement it… but then remember if this late in development they are all the sudden told “oh by the way look through ten thousand+ lines of dialogue (dos 2 reportedly had 1 million words of voiced dialogue) and make sure players with this list of tags would know about this information and edit it in and record voice lines for responses”
It just simply isn’t going to be that way as nice of a feature as it probably would be.
Now when AI starts being used to make games maybe maybe…
