The dialogs don’t make use of this feature currently, but it is here and functional. Basically, personality traits have two purposes:
- defining a “personality”, which is basically a set of dialog lines to use in events and interactions. The dialogs I wrote so far are the default dialogs, but if I were to define an “edgy” or “tsundere” personality for example, I could write dialogs specifically for these personalities and those new dialogs would be used instead of the default ones if your character has the corresponding personality.
- refining dialogs. If I want a character with a specific personality to behave differently depending on her traits, it’s also possible. For example, I could give two tsundere characters different dialog lines depending on their traits. In this case it would not be an entirely new dialog tree, but just changing a line or two. Just to add a few small details and make characters feel a bit more unique.
You can think of it as a set of tools to build a custom character. I’m probably not going to make use of it until the game is more fleshed out, but I want to keep modding and customization in mind as I work.
