Short answer yes.. This game is definitely worth getting.
Long answer. A lot of you have already said it but this game is very dated. The characters do not have any personality besides being described as Light Warriors (which you will have to interpret on your own). The story is pretty well put together but does not go into very much detail unless you walk around and talk to EVERY SINGLE npc.
Having been made in the late 80's this game was definitely amazing for its time and is a classic that should not be passed up if you are a final fantasy fan.
To be honest I was never a fan of the series and never even wanted to try it... Now that I decided to give it a shot I started with game 1 and I am hooked.
