Glad that I am not the only one playing the first Final Fantasy.
This is the second time through the game, but the first on the Origins disc. On the NES, I used the generic party (FT, BB, BM, WM) and I did pretty well. Now, I had to use the 2 classes I didn't use before, so I am using a RM, Theif, Blackbelt and White Mage.
Nobody can take a hit. My RM is my tank character as he has the best defense. My Blackbelt kills things and does more damage than the other 3 combined. I am hoping to reach the class change because once I do, I am going to be so fast and so much better. Right now, I just finished the fire temple and am trying to go through the Ice Cavern. I am about Level 27 and I probably should level up a bit more. I forgot how hard the game is. Damn hard.
