Kingdom Hearts 2 is simply the most magical adventure you'll ever expirience on the ps2.
before the actual game begins you will be playing a prologue with a new character in the game a mysterious boy named roxas the prolouge will mostly be in the form of mini games and few boss fights but you won't have the chance to enjoy the new features in the game such as the drive forms until you control sora once you're done with the prologue.
the gameplay is a lot better from the original especially the camera and what makes the game more interesting is the fact that you can team with diffent disney and final fantasy heroes and perform eye catching battle combo which will be useful in boss fights also in the game while you're battling you can press the triangle button when prompted so you can do a combo attack,dodge enemies and perform a co-op attack with your supporting characters all these new fighting features adds a special taste to the gameplay.
the level design simply catches the spirit of the disney movies just right once you enter worlds based on a disney movie you will feel amazed on how the game designers managed to translate these movies in to a detailed 3d world that stays true to the movies so i think the graphics were good.
some of the things in kingdom hearts 2 is the fact that has a lot of cutscenes wich extends the time you will spend playing the game you can't skip them and sometimes they get really long and boring.
the music in the game is no diffrent than the first game so don't expect to hear anything special the voice acting is well done and feels just right.
one of the most exciting time you'll spend on kh2 is the gummi ship levels they are fast and completly better than the one in the first game what makes it more great is the fact that you will have boss fights in the gummi ship.
kh2 has alot to offer you inspite of the many cutscenes stuffed in the game you won't lose the track of the main plot also there is a lot to do in kh2 cause you will be visiting the worlds several times after you lock it with the keyblade cause there will be new bosses you have to fight and some missions awaits you before you can complete the world 100% for example after you lock mulan's world you'll have to revisit the world again to fight a new boss.
all in all kh2 is simply so much better than the original the game won't disappoin you and it is a must buy.
