Yeah, we reviewed the Smash Bros. text top to bottom, but only used stuff that felt like it properly fit in the FE world. You can't really blame them for translating all of that stuff hyper literally in SB. Short of translating the entire source game first to establish the world setting and style (which would've been impossible, of course), they didn't have many options for creativity. So they went super dry/literal. But when it came time to do Shadow Dragon, there was no way we were going to have a place called "Akaneia" in a world like that (for example). It just doesn't fit.
In any case, you can never please everyone with name changes, but one thing I always like to remind people is that no changes take place w/o the original creators' blessing. (Sometimes they even suggest changes themselves.)
Hope you're enjoying Awakening!
