In the Rune Factory series, when you talk to a villager, a specific sound cue of the character's voice will play. It doesn't necessarily have to match the written text and really all it adds is a bit more life to the characters' emotions. (Though how awesome would it be to have fully-voiced stuff?) Is it viable to do it for Stardew? I imagine it be difficult to implement but I think it would also be a fun community project to make/gather the voices (or we can rip them from somewhere).
