First playthrough: Should I power-level?

[Mo-Nercy]

If you want to be godly, just get Zodiac Spear early. There's no need to waste away hours leveling up. Fomulhaut (the best gun in the game) can also be picked up fairly early (after beating Antlion).

power level... FFXII is too exhausting to be played twice in a row. You will be glad you got it over with easily.

amen. renmiri took the words out of my mouth
