Ok so I'm working on a little bit of procedural NPC functionality and I'm wondering if anyone has any good resources, examples, or ideas for applying something like... personality filters to text? Or, like, marked up text? The first things that jump to mind are character catchphrases in Animal Crossing and the text filters in Qud for Fish and Birds? Just thinking of assigning one such filter to each NPC generated and then the other systems can provide base text to then be presented through that filter to give it character that makes it feel both more cohesive and unique to that NPC? I've got some thoughts on ways to approach it but I thought I'd check if anyone knows of really solid pre-existing work already.
