I want to know what you guys think was the greatest Final Fantasy. It is one of the industries best franchises, and one of the pioneers of console role-playing. I don't have every title in here, so i'll put "other" as an option.
NOTE: I'm sorry that I didn't put XI and XIV as main options, I didn't because I never actually played them so I couldn't say anything about those games. If you chose XI or XIV, please choose "Other..."
Let's start:
Final Fantasy I 
The one that started one of the most popular video game franchises ever. The game was truly groundbreaking for it's time, due to it's considerably wide soundtrack, brutally challenging difficulty and genre-defining concepts. The gameplay was polished and charming, but there were still a few things to be perfected. We look at it now as a very simple game, but at the time it was one of the most envolving, engaging and inspiring RPG's. An understandable pick, since it was one of the most important games of the series.
I personaly enjoyed the game alot. Only played through it once (NES version), but I loved playing the game from beginning to end. I would reccomend it to people who haven't played it yet, and love RPG's.
Final Fantasy II 
After the success of Square's last attempt at a videogame, a sequel came out entitled Final Fantasy II. The game departured from almost everything the first one did, from setting/story to gameplay/battle system. The game was hugely considered a dissapoitment compared to the first one, although there are still many people out there who think the seond Fantasy was still an amazing adventure!
I only finished it once, so I don't remember it very well. But I remember not liking the leveling system at all, but I enjoyed the overall adventure and story way more than I expected.
Final Fantasy III 
The third game of the series was truly one of the greatest achievements in console role-playing games. The turn-based battle system was finally perfected, and it added an unique gameplay element that would become a staple of the series: the Job System. Another game that we look now as very simple, but it was the greatest RPG of it's time, given it's immense world to explore, it's huge soundtrack considering the NES's capabilities and it's charming, but polished graphics.
This is my personal favorite RPG ever. I played through the NES version countless times and once in the DS version. If you haven't played it, go...NOW!!! xD
Final Fantasy IV 
The first 16-bit game of the series was also one of the most important. It was the first one to have a really epic storyline, with incredibly envolving characters and dramatic weight to the main plot. The gameplay was the standard turn-based with a few tweaks and improvements, one of them being the addition of the active-time battle system. The game had also very good graphics and one of the greatest soundtracks on the Super Nintendo.
This is also one of my favorites. Played through it one on the SNES version and currently playing the DS version. Play it and love it, if you haven't already.
Final Fantasy V 
After IV, it was time for another japan exclusive (at the time) title. V deviated alot from it's predessecor in terms of character development, skill learning system and art direction. It also used the Job System that III used back in the NES. Dismissed by many, unfortunately, and it was one of the very first games to receive a fan translation.
I really liked this game, and I hope i'll get around to complete it a second time. They improved and tweaked the Job System of my favorite FF, but I still prefer the original.
Final Fantasy VI 
A fan favorite of the series, it has been widly acclaimed by gamers as one of the greatest titles of it's platform and one o fthe greatest games of it's genre. The game had incredible graphical improvements, character animations and original designs. The gameplay was the standard turn-based gameplay, with the addition of the Esper System. A widly acclaimed soundtrack, incredible variety in characters and a hugely envolving storyline make it deserving of it's allocades.
Though I enjoyed playing through the SNES version once, not one of my favorites. Still reccomend it, though...
Final Fantasy VII 
The most popular of the series, and one of the most acclaimed games ever in general, Final Fantasy VII revolutionized gaming. It brought, single-handedly, the role-playing genre all over the world and it brought the complex story concept to a whole new level. The game's plot was truly deserving for a book and a movie adaptation. The gameplay was also standard turn-based, but with the addition of the gamer-friendly Materia System. The game also change the way how we look at games, with it's amazing visuals, scenarios and CGI segments integrated into the action.
I respect it's legacy and what it did to gaming, but it just isn't one of my favorites. I'm currently replaying it, and i'm enjoying it way more than the first time around!
Final Fantasy VIII 
The follow-up to an outstanding game turned out to be a game with different ideas and concepts. The storyline was more centered on the main character's love story and it also conceived a more complex, deep and strategic character development system, the Junction System. The game's graphics improved drastically from it's previous installment, mainly in the character models. A beautiful soundtrack gave the game praise among the series' community.
This is IMHO the first really bad FF. The junction system just feels like busy-work and the storyline makes absolutely no sense. Not a very good game to start with the series.
Final Fantasy IX 
The follow-up to the futuristic PS1 games was, unexpectedly a throwback to the first Final Fantasy games. It brought the "fantasy" feel back, with it's medieval age and more simple storyline. The gameplay was once again the standard turn-based with a new and more straight-foward character ability system. The game improved once again on the graphic department, with more detailed characters and scenarios. Another wonderful soundtrack, with incredible variety put into it. Hironobu Sakaguchi's personal favorite Final Fantasy.
My second favorite. Played it several times, and I think it's the perfect one to start with.
Final Fantasy X 
The game that brought the series to the 128-bit era was a completely different experience from what gamers have been playing for years. The game's plot centered once again in the romance between the main characters, but with an original turn. The gameplay was once again standard turn-based, but with some significant improvements like the in-battle party change and the new Sphere Grid character development system. With beautiful graphics and a soundtrack that also took a different turn, it was praised by critics and fans.
I hate this game...I hate the man who had the idea for this f***ing game. I HATE THIS GOD FORSAKEN PIECE OF S***!!!...Sorry, rage moment. Don't play this game, if you value your sanity and patience!
Final Fantasy XII 
Another title that gave players a throwback to Final Fantasy's roots, again with a more simplified plot and character back stories. The gameplay changed completely from it's predecessors, being like a mix between turn-based and action gameplay. The License Board was the new character development system, and almost every other aspect of the old titles was put into this one like magic shops. The visuals were the best yet, even though it didn't push 100% of the PS2's capabilities. A new composer was brought to make another great soundtrack.
People give s*** to this game, but actually I didn't think it was that bad. Actually...I loved the game. I really reccomend it, for gamers who want to recover from the trauma of playing FFX...
Final Fantasy XIII 
The game that brought the series to the new generation, Final Fantasy XIII was another epic-fantasy like tale. The story took a more engaging and envolving turn, with incredible scripting and dialogue. Characters had a fitting and deep back story, with talented voice actors to enhance the experience. The gameplay changed drastically once again, to a more turn-based style battle system. The Crystarium is the new character development system, with certain similarities to the Sphere Grid. The graphics are the best yet, pushing the PS3 to it's maximum power. The soundtrack took a more dramatic turn, but still has thrilling and exciting music.
Wow...just wow. I watched so many people give s*** to this game, and I realised that they must be the same ones who gave XII s***. All of them must be FFX fanboys. This game is not half as bad as people say it is. It has flaws, and it isn't exactly one of the best of the series, but it's still an amazing title that I reccomend.
