Kingdom hearts is a great game and shouldn't be missed!!!
gameplay:- the gameplay in kh2 is really good although you will mainly be bashing the x button. they throw in other things though to mix it up a bit like when u use the triangle button to perform reaction commands. also when you gain more ability point (ap) you will be able to perform guards or counter attacks with the square button. The gameplay might be but mashy but it is enjoyable while playing and you wont really notice your just using one button mainly. 8/10
graphics:- the graphics are great. they are improved from the first kh and a lot of the main characters look mature in kh2 compared to kh. Not much else to say exept that you should not be dissapointed with the graphics because they are colourful and have a lot of cool effects while fighting and the cut scenes look good but the cg in the beginning and at the end is amazing. 8/10
sound:- The sound in kingdom hearts is good you have all the different music for each disney world and most of the voice acting is realy well done with a few exceptions ( cough.... aerith.... cough). 8/10
story:- the story is probably the best thing about this game but make sure u have played kingdom hearts 1 and chain of memories bacauze it will be confusing otherwise. 9/10
well all i am going to say now is buy this game if u liked the first one!! u wont regret it!! or just buy it if u have a slight intrest in these sort of games !!
