My personal favorite entry into the KH franchise. Booting up the game and learning you have a strict time limit to play before the game boots you out of one storyline and into the other may sound frustrating and flow breaking, the game softens the blow by giving you points based on how much/how well you did which you can exchange for boosts and buffs such as dealing more damage or extending the timer whenever you swap over. After the first world I could easily finish an entire world in 1 sitting and manually swap over without having to break up the flow at all. I am a huge sucker for themes of duality, and this game exemplifies that to a T with Sora constantly struggling with Xemnas and the nobodies in his worlds and Riku getting harassed by Ansem and the heartless in his. The main gameplay gimmick of the game is this strange SMT esque pet collection that are used as temporary party members until you replace them for better ones. Decently interesting, doesn't take up too much time if you don't care and if you do there's an entire Nintendogs minigame to mess around with them.
