dtgreene: (By the way, in case it matters, I've already chosen my party; it's 4 robots.)
Darvond: Four white mages?! It'll never work! I see you've chosen to challenge yourself today.
Many of the games I play leave the characters so faceless as to more broadly refer to the party as a whole rather than characters; even Ultima just outright calls the character The Avatar most of the time.
Actually, 4 robots is not a bad party, and it should not have any trouble getting through the game.
* Making a physically strong robot is easy; get a bunch of light sabers (or, later, catclaws) and give them to a robot. The robot will then hit fast and hard. Also, the remake adds fans, which do agility based damage to an entire group.
* There are plenty of fixed power weapons that affect a group. With any other race (except monsters for obvious reasons), these would be too expensive to use sustainably, but robots don't have that issue; one inn trip and durability is restored.
* One nice thing about the remake is that there are magical circuits that robots can equip to get magic power. Equip some of them, along with a healing staff, and you now have a character who can heal the entire party. Attack magic items can also be used, like that Flare Tome that's expensive, normally has only 10 uses, and is only briefly available in the shop (though it becomes available again end-game). Give it to a robot, and those 5 uses recharge at the inn; furthermore, this item provides 144 HP; the only item that provides more I believe requires beating a very hard optional challenge and getting lucky.
* Later on, there's a couple healing items that don't even need magic power to work well. High agility + full cure is *very* useful in emergencies.
* All this without the tedious task of raising human or esper stats to decent levels.
(My 2 robot 2 monster playthrough many years ago (playing on the imported cart) was one of my fastest due to not having to deal with slow human/esper stat growth.)
One crucial difference between my party and your FF1 example:
* Each FF1 class is assigned a specific role. Monks are heavy damage users who do not get spells or multi-target attacks; white mages are focused on healing and have very little in offensive power, except against undead.
* Each SaGa 2 race is quite flexible. Any race can be a physical powerhouse (might be harder for espers and monsters, but it's still feasible, but note that the esper will focus on AGI-based damage just like a robot would). In the DS version, any race can be an effective spellcaster (in the original, robots have no way of boosting their magic power, so they don't work as mages). Hence, single race parties can be balanced.
