For the longest time I said that too, but I got the GBA Kingdom Hearts for my birthday and it has to be the fucking coolest and most addictive RPG since Final Fantasy 6. I'm not sure how the PS2 games play, but Chain of Memories has a cool little real time battle system where you use cards to determine what actions you take, like attacking or casting a spell. the field controls feel like Paper Mario, with all the platform hopping and hitting things with a giant key, and the battle system feels like a better and more strategic version of Zelda 2. It rocks
The Summons are my favorite part, so far I've gotten Simba, Cloud (after fighting him as a boss
), and the Genie.
Right now I'm in Halloween Town
