Replay Value
There is no new game plus feature in Kingdom Hearts 2, and beating the game won’t unlock features that you can use in a second play through. And the levels are always open, so you don’t have to worry about missing anything your first time. For these reasons, the game has low replay value. However, there are enough mini games that you can continue playing the game for a long time.

There is one small piece of unlockable content. If you complete the game on Proud mode you’ll unlock a secret bonus video. You can also unlock it by getting a 100% completion on normal, but this is much much more difficult. As mentioned earlier, Proud Mode isn’t really that hard, and as the video is awesome, I recommend playing the game on this mode.

Why Buy?
Despite some issues that make it hard to revisit, Kingdom Hearts 2 is still a game that you will enjoy. It’s fun to play, though it’s not for people looking for a button mashing challenge, or an adventure game with platforming and puzzle elements. It is a game for people who are looking for a good mix of action and RPG. It will appeal to those who want to see Donald Duck set things on fire with arcane magic. And for those of you who, like me, can’t get enough of the Final Fantasy characters, it will provide you with a quick fix. But the main reason to buy this game is to tie up the story from the previous Kingdom Hearts. If you haven’t played the first game, I would urge you again to go out and buy it before playing this one. Assuming you enjoy Kingdom Hearts 1, you won’t be able to resist buying Kingdom Hearts 2.
