Kingdom Hearts CoM is a lot different than all the Kingdom Hearts and is unique in the battle system that is based off Cards.My overall opinion of the game is that it's a unigue and that I can understand why people would dislike it,Yes it is different, but it is also the only game of it's kind I have ever seen, not many gaming publishers could pull a game like this off. Sure it has low GBA graphics but many GBA games do, and if you've seen other games and watched the opener of this game, then you'd see that it took a while to make this game.
I gave the Graphics a 8,reason: Normally game characters for GBA are not detailed very well and have nothing that catches your eye about them,KH:CoM has a familiar Kingdom Hearts look about it. Given the year this was made it's a fairly impressive game.
The sound is a whopping 10, it is almost like they took sound recordings from the Original KH and placed them inside this game, It doesn't leave you sitting there thinking "That sound is boring and blocky" instead it has an interesting,more down-to-Earth feel.
Addictiveness is an 8, it wouldn't leave me staying up hours on end playing non-stop KH but it definitely will make you want to play more!
Story is a 9. The idea of Sora losing memories is good for a story, it leaves wondering "What is he going to forget next?" or "Which enemy will I face next?" However it's not quite up to par with the other Kingdom Hearts games.
Depth is a 7, the only really customizable part of the entire game is the card system, not much else.
The difficulty is not a factor up until the end, the hardest of parts is possibly (SPOILER) trying to kill enough Heartless to escape Monstro.
