Final fantasy 7 was the best of them all to me. actually its my fav game of all time period. 8 was great too but the ending kinda sucked. the only thing missing from 7 was the card game from ff8. i loved that shit. 9 was my least fav of all them, it seems like it was rushed out. ff7 had the best:
1. characters
2. story
3. magic/ability system
4. mini games (triple triad would have been the shit if it would have been in it)
5. optional bosses (cmon now, Ozma from ff9, what the hell was up with that shit?)
6. Longevity ( look at all the 7 stuff in other games. seph and company in KH, ergheiz, advent children, cloud in fft, ultima and omega weapon and the other "weapons" in other ff games and other apperances)
7. play time ( 80+ quality hours if you do all the stuff)
8. its fun!!!!!!!! ive played through it numerous times
and everything else! 7 is the shit !!!!!!!
