You will accumulate at least three of these obligatory party members:
...
-The tough-as-nails female warrior who is not in love with the hero (note that this is the only female character in the game who is not in love with the hero and will therefore be indicated as such by having a spectacular scar, a missing eye, cyborg limbs or some other physical deformity)
You Can't Kill Me, I Quit (Seifer Rule)
The good guys never seem to get the hang of actually arresting or killing the bad guys. Minor villains are always permitted to go free so they can rest up and menace you again later -- sometimes five minutes later. Knowing this rule, you can deduce that if you do manage to kill (or force the surrender of) a bad guy, you must be getting near the end of the game.
haha very true.
the age thing didnt happen until FF8 though, where the characters were absurdly young. really hated that

# Magical Inequality Theorem
In the course of your travels you may find useful-sounding spells such as Petrify, Silence, and Instant Death. However, you will end up never using these spells in combat because a) all ordinary enemies can be killed with a few normal attacks, making fancy attacks unneccessary, b) all bosses and other stronger-than-average monsters are immune to those effects so there's no point in using them for long fights where they'd actually come in handy, and c) the spells usually don't work anyway.
Wait! That Was A Load-Bearing Boss!
Defeating a dungeon's boss creature will frequently cause the dungeon to collapse, which is nonsensical but does make for thrilling escape scenes.
