Alright so i have never played final fantasy 1, well i can download orgins on psn, for only 9.99, i hear you can change the settings back to the original game, so you pretty much get only better graphics and interface.

My question:
How difficult is the game on normal mode, i can't play any ff game unless it offers a challenge, i was tempted to play Vi, or Iv, But i keep reading reviews saying it is easy to moderate, this is just a turn off simply. I want a challenging final fantasy, but anything other then tactics the graphics style looks awfull.

On a scale 1/10 Would this game be a challenge first run through? I do normally use a walkthrough, and what is the replay value of orgins.
