I have to say, this is probably like in the top 3 favorite FF. Its just got such a great world, pretty fun battle system, I love being able to PICK YOUR OWN WEAPON. I mean, being able to choose from Crossbows, Katana, Ninja Sword, Rods, Staffs, Poles, Swords, Knightswords, on and on, its just great. Kinda sucks though, since your not sure exactly what each does, in terms of benefits and such, but still, fun stuffs.
From what I can tell about weapons there are benefits for each weapons.
1 Handed Swords - Good attack speed, and damage. (Bests weapon for a tank)
2 Handed Swords - Very high damage, but slow attack speed.
Guns - Weak on the damage, but it can't be blocked or parried. Has a high critical rate.
Bows - Execellant Ranged Damage, kinda lacking on the critical hits.
Katana - Combo's galore with good damage.. I know there is a combo using the Genji Gloves, Bravery, Haste, and Berserk thats allows for a 10 hit combo everytime.
Ninja Swords - Quick attack speed, good dmg. Heals undead.
Crossbows - ?? never used them.
Staffs - Better for black mages, higher attack/magic power than rods.
Rods - Better for white mages, more mp gained, less attack power.
Measures - Also good for white mages, low damage and require you to attack allies to be benefical.
Hand Bombs - Really slow, but huge aoe damage.
