I've beaten this game several times over the years, and I keep reinstalling it and starting over again after a while. It's like a really good book, that you want to read over and over again, and even its shortcomings (there are the expected places where you have some repetitive battles to experience farm in order to level enough to make it past certain opponents) do not detract from the fantastic playing experience.
Also, I have worked in interface design and I have to say this game has one of the best-thought out, most seamlessly usable interfaces I've ever seen in a game.
I just wish there was more.
