I'm a die-hard KH fan and have been for many many years. Kingdom Hearts turned me into a video gamer. I never played for the game, I played for the storyline. When I REALLY enjoy gameplay it even surprises me, and I REALLY enjoy Re:Coded's gameplay. =)
There's just something so fun about it! I wasn't as excited about it since I watched a walkthrough of Coded as the videos came out and knew what to expect, but I've never had so much fun actually PLAYING a game just to play it and not to just move on with the story.
I believe Nomura stated that he wanted Coded to be "a playground for Kingdom Hearts fans," and I really believe he succeeded.
