yeah a walkthrough really helps. Just when I made it to that final field and the "oasis" where you can save the game, I realized I would have to spend weeks in a row just trying to defeat enemies there. Your characters just won't be strong enough to even get to the boss for a long time
Yea, Final Fantasy II (the real one) is a lot like that too... I never did finish it... Then I let someone borrow the game & never got it back... I recently started it again on PSP... I got to Astaroth, one of the last bosses, and just died, a lot.
