Just finished Final Fantasy V.
Finally!
I'm sure the game has some decent post-game content too, but honestly, I didn't get invested enough in the characters to continue playing.
Overall a good game, but there are some things I think some of the other classic pre-3D FF games did better. I'd place it on 3rd place among what I've played so far.
Probably the biggest downside to it is the over convoluted magic system. You've got Black, White, Blue and Time magic + Summons, + a few other classes that you have less of a control over how "spells" are cast". And for the final boss I've only used a handful of them. But mostly just spammed Bahamud summon over and over again. The game also doesn't encourage casting enhancing spells. So most of the spell arsenal goes unused.
Oh, and don't bother with physical damage classes towards the end. They don't do that much damage after a point, and the game literally encourages you to do summoners, with a lot of the monsters at the end being vulnerable to water, and one of the last summon you get is water based damage.
My advice for a party build: get all your members to master Red Mage ASAP. This gives you Dual Cast ability, that works for all magic types from what I can tell. Get 1 Summoner to constantly dual cast summons, have 1 Time Mage that also does Black magic, and switch that to Summon towards the end. Have 1 physical damage dealer with a White magic ability, and for the end switch him to a White Mage with Dual Cast, and for the last guy, maybe make him a tank or something. Doesn't really matter much, since you've already got everything you really need covered for the final boss.
FF IV is still my favorite, and a lot of that is due to characters and story. But next on my list is FF VI, and from what I know, that's usually the most praised among the classic FF games.
