@Bakuma1997 i played ff3 all the way to the end. most people would have stopped because of the constant job changing that you have to do early on. it stops around the final third, but you almost always need someone with magic, specifically toad and mini. 2 bosses require a specific job, scholar, which has next to no capabilities in combat, it is only so you can see what element that the boss is weak to, who will change his weakness on his next turn after being hit with his weakness. in the 3d version, the scholar has access to magic, but not in the nes version. they have next to no armor or weapons. if you got it early, it could be viable. you get about 10 minutes before this boss who requires it.
garuda almost requires you to use the dragoon job exclusively to fight him. not a bad thing since it's a good job, just requires a bit of time to get over the job sickness in the 3d ver and job money in the nes version. you'll get enough money to cover the armor and weapons in the meantime.
but most flaws of the game can be dismissed by either just getting all of the equipment in that you can carry and checking out each job when obtained and spending about half an hour making adjustments.
the biggest flaw is at the end. 2 dungeons, with only one save point, and there is an optional dungeon inside the final dungeon with several bosses and 2 shops in there. you can heal up there if i remember correctly, leaving should boot you back outside [hopefully in front of the crystal tower, i don't remember clearly, it's been over 10 years since i last played].
you have 6 bosses to fight at the minimum with 4 other bosses guarding the ribbon accessory, with only whatever you brought in to fight the enemies to heal your team with. and if you didn't know that the black belt class was the one with the best hp growth, you'll be screwed in the final battle in all versions because the final boss spams an area attack every round in the nes version and has 4 attacks per round in the 3d version. they can be mixed up and used in any order. each attack can deal 1,500 points of damage per hit. my characters were around 2,300 hp. and level 60, the same as the final boss.
about 45 hours, and i have to restart so i can get some actual hp on my characters to just survive some of the attacks.
hopefully you had a better time with the game than i did, if you played it.
