Oh Kingdom Hearts, how I've known you! Kingdom Hearts & its sequel are my most favorite games of all time. For me, I just loved the gameplay loop: going to a world/planet, smacking some Heartless here & there, then fighting a boss, then repeating that process until you save the planet. The game is so well designed that this process was continuously fun instead of boring or repetitive; I've replayed this game alone nine or ten times because of it. Speaking of that, the music... oh the music; it's wonderful! I'd describe it as a well orchestrated lullaby - especially the World Selection's theme song "Precious Stars in the Sky". So much of this game is memorable to me; it effectively helped form my taste for real-time combat games. For any of the Kingdom Hearts games to be on GOG would be an absolute delight!
