Kingdom Hearts was one of the all-time best video games ever created, thus creating Kingdom Hearts 2.

This game continues Sora's quest from Kingdom Hearts, and Kingdom Hearts Chain of Memories.  Sora, Donald, and Goofy, attempt to find King Mickey, and during their journey, they come across may worlds in which they explore.  These worlds include some old favorites, such as Holloween Town, Agrabah, and Atlantica.  New levels include Port Royal (Pirates of the Carribean), Tron, Land of the Dragons (Mulan), Steamboat Willie, Deep Dive City, and Twilight Town.

In the beginning of the game, KH2 introduces a new playable character know as Roxas.  His little story mode only lasts for about 3 hours however, and is basically a toturial for newer players to learn to play.  After that, you play as Sora for the remainder of the game.

As Sora, you meet mysterious Hooded people called the Organization 13, who are up to something for you to find out :)

Time to get technical.  Kingdom Hearts has many new improvements.  Here are a few that I'd like to point out.

PROS
1)  The camera is much improved from the first game.  The main change was the buttons used.  The first KH used the R2 and L2 buttons, which were slow and not very helpful at most times.  Now, the layer controls the camera with the right analog stick, which is much more accurate.  It isn't perfect however.  When you are fighting a fast enemy, or near a wall, the camera may not work.  Don't get me wrong though, it's an awesome improvement.

2)  Sora now knows drive bar moves, which are very powerful combos.  With it, you can deal lots of damage to a spacious area.  You can also fuse with Donald and/or Goofy to power up even more!

3)  The game graphics are perfect.  It really pushes the [...] old PS2 system to it's limits.  YOur game play should not be disruptted from this though.  The worlds are awesome 3D worlds with nice colorful enemies.

4)  The Gummiship is a lot better too!!!  For KH fans, many hated the Gummiship.  Now it's much faster paced.  You fight tons of enemies from all directions, all at the same time, making for a better challenge and loads more fun!  There are many upgrades to choose from too, so there are endless ways to customize your ship.  Also, for people not big in making their own ship, KH2 has premade blueprints to use.  During the gummiship flight, you can also fight bosses.  There is also multiple ways to reach a destination, not just a straight path.  Lastly, you can keep track of your Gummiship high scores!  This is a great thing to do if you find yourself a little board with the main story.

5)  Another big thing that bugged people in KH was the cutscenes.  If you've seen them already or don't care to watch them, or if you are in a rush to find a save point, too bad.  You had to watch the cut scenes.  KH2 changed that too.  To skip a cutscene, just hit start and go down to "skip cutscene."  I loved that change.

6)  Jiminy's Journel is extened and more detailed.

7)  The game has great replay value (about 100 hours if beaten 100%) to keep you busy for awhile.

Too good to be true, right?  Right.  KH2 isn't perfect.

Cons
1)  KH2 seems much easier that KH.  I mean much easier.  As you level up and learn nice combos and magic, the Heartless/Nobodies surrounding you never really increase their stats.  Therefor, one can eliminate his enemies with ease and taking the challenge out.  If are/were a huge KH fan and played KH before, I reccomend trying "Proud mode," which is "hard mode."

2)  KH2 is an action RPG, but it may have too much action.  In KH, magic was required for certain fights.  That's not the case with KH2.  No magic is neccesary, and neither are the special power combos.  All you need to do to get through the game is do some "X mashing."

3)  This isn't really important to the plot or gameplay.  I did notice though that KH2 had very little scenes with Final Fantasy characters and a little too many scenes with Disney characters.

4)  This isn't really reated to plot or gameplay.  The characters in KH2 still have "robotic movements."  In other words, before a computer character in a cutscene could run, he had to turn.  The movement just didn't seem natural.  But hey, maybe I'm just being too picky.

5)  The story line was a little too tied into the first two Kingdom Hearts games.  If you havn't beaten them, or at least played them, you may not get the story.

6)  There is little exploring in KH2.  In fact, there is very little strategy (except boss fights).  The game is fairly straight forward, so if you are looking for an in depth, "I gotta think" game, this isn't the best choice.

7)  There are lesson summons and magic abilities than the first KH.

All in all, KH2 is a great gaming experience.  I should warn people however, that it is recommended only if you have background of the first two KH games.  I few tweaks here and there and KH2 would be perfect.  I think anybody could enjoy it, and expect something great.  I'd give it 4.5 stars.
