Perhaps a controversial take, but this is one of the better KH games. At this point, it was still a weird experiment by Disney and Square, and so hadn't yet become a victim of its own success - the plot was still comprehensible without needing to both play dozens of games across multiple systems and then read wikis for hours. The gameplay is mechanically much simpler than later iterations, but the core action combat is already here. The bosses are interesting since you get to fight a mix of Heartless, Final Fantasy characters and Disney villains, and the OG soundtrack is iconic.
