From the official site you could hear what Montezuma calls himself something like "Imperorin" - clearly a european-based word. I understand what modern nahuatl has a lot of European adoptions, but I'd prefer to hear more native even if less precise words. Looks like they have the same thing with Ancient Egyptian - it seems to be based on modern coptic, which has rich arabic influence. But I'm not a specialist here and it doesn't sound disturbing for me. Anyway, that's not a first priority feature, of course.
