im probably gonna start replaying this game and actually beat it pretty soon, and i just wanted to see if anyone can give me any useful tips. the first (and only) time i played it, i got to N-Zone, but my characters were just to bad to proceed. im not sure exactly what was wrong, but i was abuot level 40, and i think i had only mastered maybe 2 jobs at the most per person. do i need to master more jobs beforehand, or just level up more?
