IGN's got their review up: 8.8
The just-released Japanese version has full English language support, by the way. I got to play a good chunk of the import at the office today, and I'll say this: it plays like a dream. On the technical side, everything is perfect; the graphics and sound are exactly like the SNES original, and there's zero movement/menu lag or slowdown. Seriously, it makes one cry that Final Fantasy VI Advance might've aspired to be like this had it also gone to DS.
I tried out both the DS and Classic modes of gameplay. I'm still trying to decide if I like the aesthetics of DS mode or not. On the one hand, it's fantastic having a full view of the battles by dropping all the menus to the bottom screen. The downside is that you have to train your eyes to flick back and forth between top and bottom screens to play properly. The touch screen aspect seems to play well enough, though - they've made the command boxes nice and big so that it's easy to cycle through attacks, techs, and combos. The Classic mode is exactly what it is, but I wonder how many people are going to bitch about the slightly smaller font size that they've chosen to use? In any case, the customizable options on display here are expansive, and will surely guarantee that everyone will be able to play the game their own way.
I'll have impressions on the localization changes after I dig into the U.S. release next week, but I have noticed that much of the weapon/item names have been changed, much like FFVI Advance. It's hard associating Revive with Athenian Water now.
