Let me preface by saying I'm not a big Persona 4 fan (never played any of the games except for Arena which I really don't think counts).  I picked up this game because I love the music/rhythm games, especially those that come out of Japan.  I'm a big fan of the Bust a Move (or Bust a Groove in the states), Parappa, Um Jammer Lammy... those sorts of games.  The game itself is very fun and easy to pick up.  The mechanics involve hitting notes that go over the up, left, down dpad and/or the Triangle, Circle and X buttons.  The analog sticks are used as well, but are optional notes that the user can hit.  I skipped through most of the story as there is A LOT of dialogue (as one might expect) and I'm playing this game on my commute to and from work, so I would rather get in some gaming rather than listening.  The LE contents are somewhat forgettable.  The keychain is cool if you're a hardcore Persona fan, I guess.  The carrying case is useful, if I used a carrying case, but that's just another clunky pouch I would need to worry about while on the train or walking... I prefer to just put my Vita in my back pocket or in my backpack.  The Vita skin is alright, but I doubt I would use it, even if I had PCH-2000 model.  The wallpapers are just obtained through the Vita web browser.  The only thing that I found of use were the DLC codes and after looking at the other outfits available in the PSN store, I'd rather have those instead, but oh well.  So, if you're a fan of music/rhythm action games, I definitely recommend this.  If you're a Persona fan, you'll probably appreciate and enjoy the LE bundle more than myself.
