Final Fantasy has always had pretty bad dialogue (though there's something strange that I love about it sort of like Escape from New York or Star Wars)... 9, and 12 were exceptions and had pretty good dialogue imo. Obviously since Lost Odyssey was written by sakaguchi (aside from the dreams which are well written) are going to sound the same as 1-5.
Persona (atlas games in general) and ghibli (haven't played nino kuni) have some of the best dialogue in the industry.
