I agree with Formy. Battle dialogue I could take or leave, but why, oh, why would anyone remain silent when crossing somewhere like the Sandsea, for instance? There's nothing to look at, the only thing to do to alleviate the crushing boredom would be to talk. But, no. As always, when roaming the vast expanses they all remain stoically silent.

I'm not saying that their conversation has to be all "Yay, we're all besties!". People have long conversations with people they don't really know or like all the time! Would it be so weird for the party in XII to talk to each other, even if they didn't much care for each other outside their specific friendship groups?
