They expanded character creation a bit for existing choices, but not by much. There's a lot more voice types instead of just three that 1.0 offered, and you can make your boobs small if you want. But there's still only a few hairstyles per race, way less than competing MMOs.
Uematsu's version of the prelude for XIV 1.0 has been removed it seems, in favor of this 2.0 prelude. They're both really good renditions, but I wonder if they've decided to go with an all new soundtrack and abandon 1.0's music.
I'd be lying if I said I wasn't interested in 2.0. Like 1.0 before it had its miserable launch, I really do want it to succeed. I'm curious to see how the adjusted combat system works.
