I just got the game today, so I'll give a first impression synopsis.

Battle System: This is the kind of fighting I've been wanting in RPGs for a long, LONG time. The multiplayer capability is a rather fun twist as well, the moves are easily executable, basically Smash Bros. moves, and the combat system is easy to master. If I had more characters with healing magic, that'd be great, but that's just me.

Storyline: I'm getting some major deja-vu in this department, it's looking a lot like the "Cycle of Death" from Spira in FFX, though I'm not totally sure as I haven't found out enough about the whole "Chosen One" bit to know what exactly it entails.

Graphics: Somewhat chibi-ish, but not bad. The anime cutscenes are rather good, and the battle's aren't that bad. The character outlines are bold black, and really noticable, which is an interesting technique that I'm not quite sure if I like or not.

Playability: As I've been playing it pretty much nonstop for about 4-5 hours, I'd say it's pretty good.

Other Notes: This is, so far as I know, the first duel CD game for the gamecube, and it boasts of having 80 hours of gameplay (though we'll have to see about that). Also, there are no random monster encounters, you see them on the field. Sometimes they run, sometimes they charge you down, it depends but you can probably avoid battles if you have to (though I never do).
