It really comes down to what you are looking for but FFIII was a pretty inventive game that utilized the job class system in some interesting ways by building bosses and dungeons around making sure you use the right party set-up. I find the game really picks up once you get the boat and can really explore the world. I can't really tell you if it worth it to keep playing and will get better unless I understand why you got bored in the first place, I personally never had much of a problem plowing through it but I tend to favor retro titles.
