What Kingdom Hearts Game do you like the most and why?

I like Kingdom Hearts 1, because of the awesomeness of the Glitch in Destiny Islands in the End Of The World nice, smooth gameplay, and well, its the first game, and i dont see why NOT to like it! but im sure after KH:3D comes out, it'll probably be my next favorite title

Whats yours?

This is very hard for me to choose, as I like different games for different reasons.  Overall I'd probably say my #1 favorite was the original Kingdom Hearts, just because it's well-rounded in gameplay and story (not to mention it was the first. )  Birth by Sleep and Re:COM are close seconds, though.

Com AKA: Most people's least favorite

I felt Com actually did so many things well. For one it was on the gameboy advance. The gameboy advance isn't super amazing hardware like consoles are but they used it so well for making Com. They were able to fit jumping, dodge rolling, sleights, attacks, pausing, menus etc. all on 6 buttons plus the d-pad. That's pretty amazing imo. It was of course portable. Heck, they even had a couple of actual cutscenes on there. In a gba game. I actually luv the card system. It's a good way to make the player think compared to the usual hacking at an enemy until it's dead. The story was also great as it introduced important elements to the series (like the organization and Namine) while remaining a well written tale. 

I just realized my answer was insanely long

KH2 and BBS...

 

KH2: STORY STORY STORY! You just gotta love the mysterious plot!

 

BBS: They introduced the new batteling system for KH which was really awesome... and you got the chance to see some boobs

My favorite is Kingdom Hearts 3D Dream Drop Distance. The graphics are the best, the flowmotion is crazy, and the storyline enriches the whole series and gives the impression that KH3 will be better than all of the KH games.

Kingdom Hearts I/KHFM hands down. It was my first KH game and has the greatest sense of magic. From beginning to end your filled with anticipation and questions.

"What's with this giant key?"

"We've got to find Riku and Kairi!"

And not to mention the 'Simple and Clean' Opening, the first time I saw it my jaw dropped from sheer awesomeness.

Kingdom Hearts 1. It just did everything right.

I'm surprised how much love vanilla KH2 has gotten here (I personally found the game to be a total let down in terms of story, pacing and difficulty).  As for my favorite game it has to be Birth By Sleep, had an interesting cast of characters, great pacing, tougher difficulty, and a great tweak on the game play with the command decks.  My second favorite has to be KH2FM, since it manages to improve the game in almost every way from balancing the op combos (reaction commands, drive forms, etc..), increasing the difficulty (granted all they did was give 1/2 HP and double enemy damage in critical mode), and bringing more compelling post game content (vanilla KH2 had a dramatically easier Sephiroth, and a broken coliseum vs. Org XIII rematches, Mysterious Soldier, new dungeon, mushroom XIII challenges)

my favouite one is the one with rumble racing
