tactics had a wicked job system very much like FFV. I think tactics did take it up a notch though. Having played both a lot, and liking them, I have to say that the job system lends itself better to a strat-rpg than to a turn-based one. My point's seconded by the scores of strat-rpg games that came out after it that capitalized on that type of system. Not to say there weren't any strat-rpgs with classes before FFT, just that FFT made it more popular. I've clocked 200 odd hours into one file of that game. When you add all my clockings together, I think the number's pretty huge. It's a very deep job system, and fights to not get tiring.
