Mine was FFX. It took me about 150 hours once I got everything!!

XI as you can't "beat" it.

plus I have more playtime on that than all other final fantasies combined.

FFVII, seeing as i was 9 when i bought it, it took me over 100 hours to compelete, and i missed a whole load of stuff like alexander, loads of materia and so on.

Hmm, I would have to say FFX.. Considering I played over 100 hours on it and still didn't complete.

FFIX, since it took to damn long to learn abilties with weapons. Proably took me 110 hrs on all 4 disks.

Took me around 50hours with FFVII, 80 with VIII, 40 with IX and around 80 with X. But I could've beaten VIII sooner so it would have to be FFX

Checked my playtime on FFXI today.

it was only 20 days. :'(

FFX took me the longest to beat with 100+ hrs first time around

FF-X took me about 130 hours to complete (including Black Aeons, Nemesis and stuff) ;)

1st attempt at '7' 45 hours very little done
2nd 100 hours got most of everything
3rd attempt still trying to 100% it all.......
Damn those chocobos

The only FF I've beaten is 9 = [

Honestly, mine was FFX-2 (though I find this game the worst in the ff series). At first I finished it quickly because at that time, I wasnt aware of the 100% completion and I just kept on following the hotspots (stupid me). But when I started doing the 100% completion, it took me more than one month before I was able to finish it. Some missions are just so hard to complete and the part wherein u have to finish all 100 levels of the Bevelle Secret Dungeon..that really pi**ed me off! It's such a waste of time and I really hate that part. SO yeah..x-2 took me the longest to complete.

FFVII. I completed every sidequest, beat all of the weapons, got 99 of every item possible, maxed out my gil, and leveled everyone through the roof. It took about 100 hours total.

FFX, because i was trying to get everything, and I was having trouble finding the Jecht Spheres, so that was about 100 hours, other than that I've taken several hundred hours of FFVII at a time.

FF7 - about 40
FF8 - about 75
FF9 - about 40
FF10 - about 70

But I am not really the type to do all the side quests and collect everything unless they really help you progress in the game.

VIII took me three year becuase i borrowed it from a friend and i had a crappy generic memory card so my data kept getting corupt so then last winter i finally got a new memory card and found ff8 at best buy and bought it and beat 8 3 months later.

FF8 took me the longest. I was 13 then, and it took a lor of work leveling up the characters to 100 each, and their ultimate weapons and such...

FFIX took me the longest. Although it was one of the easiests.

I would agree FF9 is probably the easiest my brother even finished it in about 40 hrs with no guides when he was only 11.

FF7, I think. I was certainly playing much longer after I bought it than any other FF, but maybe that's because it was my first.

Now if we are talking just to beat it FFX. But to collect everything FFVII. 98 hours was my total for everything on VII. FFX took me only 50 hours to complete with everything.
