i still say FF11 should not have been part of the numbered series. FF online, i understand completely. not 11. they broke my damn chain. i have 1~10-2 and then 12. tsk.
as far as overpowering, ff8 was easy to abuse, but to the novice player that just played the game like any other RPG, even with the occasional powerleveling or two, the game gave a good enough challenge. given that the enemies leveled up the same time you did (or atl east the average of your team members).
but yeah, i still remember having an allchara@lvl100 file for ff8. in conjunction with that, i also have an allchara@lvl32 file (at the end of the game of course) for ff8. xD
ff7's story still stands out in my mind, especially since i spent countless hours playing and replaying the game just to find new things. xD
ff9, i love it. that simple. story and gameplay took everyone back to the roots, albeit everyone was stuck to the same job. but that negligible.
ffx, one of my favorites in the series due to the game being on the ps2 and the storyline. i love every moment i was playing that game. i especially love the ATB battle system and the mid battle character switches. it was quite innovative. :) i am one of those who rearranged the sphere grid (150hours on my file) to have everyone be everything and be @ max. i also have a no sphere grid run file, just to offset it i guess xD.
ff12 was good. but nothing too fantastic. it is quite true that the characters feel a bit detached.
oh before i forget, ffx-2. it was a so-so game. it tied up the story of ffx. that's all.
