The biggest appeal to the FF collector is that this CE is limited to 5000 copies and was only available from Square-Enix's online store. It was sold out for while before the actual release date.
I tried the demo at PAX and really enjoyed how they updated it from the first game. I felt like like the first title in the series wasn't super strong, but the music was good, and that's usually enough for FF fans.
I'm not a big FF person, but I enjoy rhythm games and gameplay-wise I felt it was lacking.
The sequel implements some newer stuff and the visuals looked pretty good. I have yet to crack open the CE but I will probably do so soon.
If you don't need all the extra goodies housed with this CE, it'd be fine to skip/wait for this game to get cheaper. I'm just a big CE person, ha.
