Admittedly, I do prefer the JP voices usually. But that's mostly if those were the voices that were first available. But, that applies to any language. I prefer NMH in English, even though I adore
everyone they got for the JP cast (it's seriously like, at least four or five of my favorite seiyuu).
However, I do think it's silly when people have no appreciation for other VAs (western or otherwise). Tara Strong will always be one of my favorite VAs, and I love Quinton Flynn a lot.@Hawk
I don't think it's any Nintendo game, just certain cases. Mario and Zelda are fine the way they are to me, but I do appreciate and love having voice acting in games like Xenoblade, certain Metroid titles, etc.
But to me, this isn't limited to Nintendo. In Atlus titles, for instance, Persona needs voice acting, but I prefer SMT (main series) and Devil Summoner to not have voice acting. Just like I feel voice acting would fit in Trauma Center, but not Etrian Odyssey.
