Final Fantasy 1 is a standard fantasy adventure, main "villain" had the brilliant idea to time loop immortality so he would forever be killed and sent back and killed over and over, brilliant fucking plan that was.

Final Fantasy 2 introduced more story and character detail and has a pretty high death count overall with half the party (There's replacements.) and several side characters being killed off over the course of the story as a mad emperor is vying for godhood.

Final Fantasy 3 is back to being more cheerful again introducing mechanics like the job system.

Final Fantasy 4 is more about Cecil and his redemption having taken these crystals from the people.

Final Fantasy 5 has some moments but then the translation for the main character was Butz and it all goes downhill although Bartz was used for later versions, more adventure and less story driven for the most part as I remember.

Final Fantasy 6 went big time on characters and storytelling though the JP version apparently has Kefka more as a clown and for the US version he's a dark comedy sociopath due to Woolsey making some changes to the translation though aside from Nintendo censorship practices it seems these were pretty well regarded overall.


And then well Final Fantasy 7 started on the SNES I think but there's only some early images from this version and then N64 but it was doomed when Nintendo opted out of their deal with Sony and having a disc drive so lacking storage space between a 600 MB CD ROM and a 40 - 60 MB cartridge though later in the consoles life larger sizes were introduced.
(Happened with the SNES too, I think it was 4 or 8 MB initially and then Tales of Phantasia is one of the biggest cartridge sizes at 48 MB due to voice acting taking up a lot of space though it's used sparingly.)

That's meant to be a darker game though Cloud comes along as whiny and emo for much of the games story and Aeris is a bit of a split with some disliking her and some liking her plus her scene happens a short while after event where Cloud himself beat her up a bit though I think it's an optional thing. (Probably going to be another cut for the remaster along with a certain route in the Honey Bee in with Cloud and seven+ dudes in swimsuits and complaints about it hurting.)


Final Fantasy 8 is a clusterfuck that is sorta serious at times and then goes way off the deep end and back and then can't really decide what to be, ending sequence is a lengthy mind fuck that makes no sense at all far as I remember.


Final Fantasy 9 is back to the traditional classic formula and has some dark moments including a lot of death and destruction but the villain characters kinda ruin it with Brahne being a living mount of blue fat and Kuja well he's wearing...a speedo/thong thing and is probably the most feminine dude in a JRPG, ever.
(And is mostly whiny and emo to boot complaining all the way to the end and fighting a proper end boss.)


Final Fantasy 10 is back to the main character having some really cringe worthy emotional issues and problems and then when a player does everything right you're reward is that the fucker comes back??

And X-2 is well it's, different.

I don't know too much about the MMO that is 11 though I heard once they started updating and improving it the game had quite a loyal fan base though then further updates kept changing things around but the game is still available but we'll see for how long I guess.


Final Fantasy 12 and we're back to a kid protagonist because publisher or exectuve meddling with the real protagonist or what was originally planned as the protagonist relegated as a side character in the players party.


Final Fantasy 13 sees the entire party whining and complaining about one thing or another going through various trials.

13-2 continues much the same and entirely obliterates the idea of a happy ending.

13 Lighting Returns begrudgingly gives it back but the player has to work for it now what with time limits and various mechanics being in play and not just for optional side content this time.


Final Fantasy 14 well it's another MMO and Square basically made a CGI where the original version was thoroughly killed off in preparation for a full reboot, kinda impressive and I heard the reboot was pretty successful too.


And then 15 having four dudes driving to dude #1's wedding with some story spliced in through the games chapter based progression but it's disjointed due to cuts and some chapters being a bit rushed and shortened even if the DLC episodes and patches have tried to improve it a bit.

I haven't seen the full game though but I heard it picks up in the later chapters but then it ends so overall the reception has been pretty mixed and having been rebooted once or twice didn't help.


I don't know too much about most of the side games (Not that the above summary of the main ones is all that great either.) but there's Type-0 which revels in blood and gore but the entire class-0 is by plot almost dead to emotion and it mixes in goofiness with serious moments as pretty much every single fucker in the game dies in one horrible way or another and that pretty much goes for the player too realizing there's more requiring NG+ and sadomasochistic levels of grinding and repeating the game all over to see the other half of the story, though that could just be how I see it.
(And then a third time to driver it even further so you get a short little samurai sequence of a potential idea for a sequel that will probably never be.)


And World of Final Fantasy, fourth wall being the first to die here but you do have a mandatory bad end and there's some darker content in-between but it's overall too humorous and self-aware to register as being dark at all even some of the bigger story revelations.

He actually does grow up, in a way, takes him to his 30's though.

I guess the ending sequence is meant to establish that squall was actually killed during the end of disc 1, he actually died. And because of the sorceress magic caused him to be stuck in some sort of limbo he created for him self. And once you beat the final boss, squall ceases to exist anymore in whatever form of energy was still there. This is why disc 2 and on seems "disjointed" or rather like things or unreal or in a dream and there are alot of odd things. Or that's what I think at least
