Likes: The amount of game play (27 hours)
Plenty of Cutscenes
The character development that was lacked in KH2
The interaction with the other Org Characters.
Amazing plot
Organization Moogle
The Panel System
All of those ones that you mentioned. :3 Plus these:
Dialog between members. This made me love Xigbar SO MUCH MORE (his giving nicknames like Poppet, kiddo, and tiger) but Demyx actually got bumped down my "favorites" list for reasons I'll list below.
Roxas, freaking out on a mission and wanting to RTC: FFF I WANNA RTC RIGHT NOWWW
Xigbar: Well, why? You leave the toaster plugged in? >: D
Roxas: >:[
OHHH OHH and how Roxas's superiors weren't afraid to talk down at him AT ALL and put him in his place! :'D
Roxas, in a recon mission with Vexen: Wow, I wonder what they sell here?!
Vexen: That's your job to find out,
idiot.
(WHICH IS WHY VEXEN IS MY 3rd FAVORITE MEMBER <333)
Yeah. The script, mostly. It made me SO HAPPY. C':
And using the Nimble++ gear. That gear was my best friend from the moment I found it, only unequip it for Mission Mode when I'm playing as members other than Roxas or Xion.
I disliked:
Demyx. His laziness/cowardice/obsession with sitar. It was cute for about five minutes and then it got old
fast. :| Sorry, Demyx.
Saix, he was a big jerkface, I hated him. AND NOT EVEN THE JERKFACINESS I like about Larxene! D': Saix was just...he was just -evil- in this game, I swear.
Sometimes the camera got -really- wonky and weird at the worst times ever. Sometimes I couldn't see what I was beating the tar out of. But other than that it was great; it behaved about 90% of the time. Easy to use.
Some of the bosses, I hated. Mostly giant Heartless bosses. The dragonlike ones irked me to no end. I hated the fortress-like one in Beasts Castle, I HATED that thing that ate you in Halloween Town (thing gave me FITS) and that sand thing in Agrabah.
But that's still not enough Xigbar.
What the heck? Are you kidding? There was a -ton- of Xigbar in this game. Not to mention he's gonna have a bigger role in his appearance in Birth By Sleep, according to Nomura. Xigbar had a HUGE role in here, especially considering how he sees Xion.
