So I done a little searching and, from what I can tell, there's no concept page related to idle dialogue. However, there's already an idle animation page, so instead of going straight to the creation process, I figured it best to instead ask between whether it's more suitable to lob idle dialogue in with the idle animation page, given that they're so similar. Or to go with creating a separate page altogether, since many games usually don't feature both, or at least there's certainly still plenty that have one but not the other.
So, what say we GB community?
EDIT: Page up, so yanno, add some stuff!
