Haven't played DDD yet, but here it is:

1. Kingdom Hearts : The original is still the best to me. As to the above post about clunkiness in your replay, I do agree with you. However, if you continue on it will stop being that way with the more abilities you get. And that's almost another reason I liked it in my recent replay. It was almost like you were learning how to battle right along with Sora.

2. BBS: I think this game is much better than KHII. I also think this is the second and only "amazing" KH game. The others are really great (save one) and more fun and addictive than most games out there but have some flaws.

3. Kingdom Hearts II: Great great game, but really only if you beat CoM before this. Also by far the most fluid battle sytem in the series. My only real problem with the game were the world by world storylines. There was some pretty cheesy and forced dialogue that was kind or hard to get through even for a KH game.

4. CoM: Say what you will, but if you really get into the card system, this game can be a blast to play. Also the bosses took some real strategy and I mean this game might have more storyline used throughout the other KH games that it may be the most integral piece to whether or not you like KHII and the other games after it.

5. 358/2 Days: Good game, but the graphics especially for a DS game were pretty shallow save for the cutscenes. The story was really good except, to me the entire Xion character. I'm still trying to wrap my head around her ending. Message me if you actually have a detailed explanation on it. I'd like to know actually. But other than that, it was fun albeit repetetive.

Coded: This to me is not a good videogame. I was super-excited to pick it up as it is a KH entry after all. Struggled to get through the crap storyline and awful bad guys/world set-ups. The only part I may have liked a little was the throwback ATB system in the Coliseum. Other than that, this was just a money making venture imo.
