If you like dungeon crawlers, grinding, and a challenge, FFI is definitely worth your time. But if you want a detailed story and characters like the later FFs, you probably won't enjoy this game nearly as much as others have. Still, it is a fun little game and worth playing if only so you understand FF's history and all the references to it. One option then would be to play a later remake of the game, such as for the GBA, which is much, much easier than the original NES game (or the more faithful PS1 version), and so requires less grinding and frustration.
