Funny you mentioned the BLADES Barracks interior theme, I was just sitting back listening to it when I read this. It's pretty pleasant. I don't necessarily dislike the Primordia theme, but I guess I can't help but compare it to Gaur Plains and it's just not as good to me.
The localization so far hasn't bothered me, other than Tatsu being, indeed, pretty annoying. I liked the Nopons in XC better by a mile. I do hope we come across another colony of Nopons that's as magical as the one in XC.
Thanks for sharing your thoughts, though. I realize while I'm typing this that it took me roughly ~15 hours to really sink myself into XC (because at first lots of the systems were confusing), and I'm still only 12 hours into XCX. Things are progressively feeling better, but, it will probably be to my benefit to not try to compare this game to the original every step of the way.
No problem, man. XCX is a different beast of it's own, but I'm sure you'll find your footing with it as you progress through the game. (Getting a license to pilot a Skell is such a rewarding experience, if you ask me.) And, to be honest, it had taken me 30 odd hours before I could get into the original Xenoblade Chronicles, so it's a plus that I was able to get myself engrossed into XCX in a third of that time.
I think they got a solid cast of voice actors and actresses for the game, including getting Mary Elizabeth McGlynn as one of the selectable voices for the female avatar. Caitlin Glass voicing Elma is also great, as I was first exposed to her voice work with helming Winry Rockbell in the English dub of FMA: Brotherhood & it's OVA. (She also voices Cammy in Street Fighter IV & Street Fighter V, if I'm not mistaken. )
Spoilers:
You will actually encounter a couple of colonies of Nopons in the game; one is a group of traveling merchants & another that houses Tatsu's extended family.They actually scold him for being such a flake, which is great if you hate the chunky loud mouth.
