Local NPCs having voice overs, that would be annoying. I was fine with FFXIs way of story telling, music drove the emotion of the moment, not the voice acting. I wouldn't mind certain cutscenes to have voice overs like they do now, just not driven by that notion entirely. FFXII voice acting was good. Kingdom Hearts series... not so much. FFXIII - I'll pass on the US voice overs.

If this was a single player I'd see it more viable, and used in more areas. Simply put I don't want to be hearing the same story from the repair npc every single time I visit. ( just an example )
