Well, apparently this guy loved it.

Yep. I played it with no problems, I know is 15 fps but who cares. :P

No headaches?

no

Nope here too.

No, it's quite frankly a disgrace to the series name, it's got horrible AI for combat (I had REAL issues getting dumber and dumberer doing anything that resembled tactical thinking), the story is so overly convoluted and awful that you'll forget it by the time it kicks into actual gear. It's about 20+ hours of corridors (And that's if you can power through the whining without grabbing your head.) and by the time you can get subquests you probably won't even give a shit about it anymore.

Imho, it's just not a good game. Since Squaresoft has become SquareEnix, the FF series is &÷#$%×.
Play FF I to X, each is really enjoyable.
In XIII, you have a bunch of $#!@fools yelling at each other like a bunch of unemployed alcoholics debating over a teen-pregnancy. Horrible.

Please, do not let all of the hate turn you off the game completely.
Honestly, I think you should probably watch some commentary-free videos or something of the game to help you decide. Make up your own mind as to whether YOU personally will enjoy it!
People have very different opinions of it. Most people seem to hate FFXIII, as is evident from the other posts. Personally, despite its flaws I really enjoyed my time with it! I'm speaking from my experiences with the PS3 version, so I can't comment on exactly how good the Steam specific version is, but assuming it's not too different, I'd like it.

I'm not saying that you'll love it, or even like it or anything, just that you should keep an open mind and do a little research in a few places before making your decision. Don't go purely by the negative comments and let that bias you or tarnish an experience which you may well have enjoyed! :)

Okay so let's address a few things regarding the game itself:

Probably, first of all, I should mention that the game doesn't really *feel* like a Final Fantasy game. If you're going in looking for an open-world, classic JRPG filled with light heartedness and Chocobos, you'll be disappointed. The game should be considered its own game. It's own title, separate from the rest of the Final Fantasy series.

The game IS incredibly linear, and if you can't get past that, you probably won't enjoy it. The game offers next to no exploration (there is a bit near the end), no choices or decisions. Ultimately, it's very much like a long CG movie, with gameplay segments in between.

So, that brings up the questions, how is the gameplay? And, more importantly, how is the story/characters?
The gameplay can be fun... but monotonous and tedious too. At first it seems fast paced, action packed and like a more streamlined version of regular Final Fantasy gameplay... but delving deeper, it starts to become a bit... too streamlined to the point where you can get through many battles just by repeatedly pressing 'x' (or the equivalent for PC). It does become a little more involved as time progresses, and if you actually want to get through battles with reasonable ease, there is a bit more skill involved in choosing the right paradigms, and what not, but ultimately, the gameplay isn't a strong point. Let's face it though, even some of the best JRPGs can have boring gameplay.

The story/characters? Now that's where I'm likely going to go against everyone here.
I did like them. One gripe that people have is that the game sort of throws you into the deep end, without really knowing what's going on, and the characters use a lot of terminology which you don't have a clue about. I guess this is fair, but I think one can pick up the nomenclature pretty quickly, especially if you make use of the Datalogs.
I found the story overall to be about as good as any other Final Fantasy game, with the basic 'save the world' plotline underlying it.
It can get somewhat convoluted at times, but as a whole, it was pretty good.

The characters are where I think the game shines though, especially in regards to Lightning and Hope and their forming relationship. The characters are not your typical heroes, and initially you may well not like them, but slowly but surely, you warm to them, as their unique elements and intricacies are revealed.
Despite what people will say about Light being a shallow clone of Cloud, she's so much more than that. Yes, she is cold and stoic and reserved early on, but soon she begins to open up and we find a perfectly good backstory, that makes her 'her own person'. Her motivations become clearer, we learn who she is as a person and why she's so cold. I eventually found her to be very relatable.
Similarly, Hope comes across as bit of a whiny Squall-esque character at first, but again, in time he becomes a much deeper character, with perfectly understandable motivations and reasoning.

The relationship between the two is what I think was the best part (and probably what the game ultimately focusses on the most). Lightning and Hope are two sides of the same coin - Lightning has lost her sister, who also acted as a pseudo-daughter (after the death of their parents) and Hope has lost his mother. They fill the void for each other and a somewhat bizarre mother-son relationship forms. For me, it was one of the most interesting elements I've seen in a Final Fantasy game.

The other characters also have their own developments and quirks, which I won't go into now, but overall I think what starts out as an unlikable, cold group slowly become a very relatable cast.

Of course, you may play it and find that you completely disagree and hate the game, as many have. And that is fine. These things are always subjective, and perhaps when I played it I was just in the right place at the right time to enjoy it as much as I did. Perhaps some of my past experiences helped make it as relatable for me as it was.
That's why I think you should probably watch some videos and read a wide variety of comments about it, not just the negative. :)
Anyway, I hope I helped, even if it was just a tiny amount!.
Regards!

^ i dont hate the game
its just avery very very bad game
and no amount of sugar coating will hide the fact that its bad

Dumbest design decision ever: You only control one person without the option to switch during combat. 12 sucked but at least you could jump over to a character to properly utilize skills instead of letting the retarded AI keep running things. In this one they went full retard. You'll watch the next game play fully without any option to control anything.

I do not agree here.
IX might not be as enjoyable to some, but that is mainly because it was made for those who played the very early instances.
And FFX has a great story with deep characters. Voice acting might have its flaws (you can always turn to Japanese with subtitles) and so does IX have its flaws, but they are still good games!

disagree there
9 doesnt knwo what it wants to be

and the story of 10 is insipid while th characters are paper thin and grating

Why do you think FFIX 'does not know what it wants to be'? It clearly aims at being a classical Final Fantasy - and it does not even make compromises here, so please explain?

And saying that FFX characters are 'paper thin' is just plain wrong. You get to learn the background and personal motives of every single character without feeling shoved down the throat. And the story stringently connects all patterns of Spira. It contains many interesting and plausible plot twists that keep attached. Are you sure that you really got the full picture of the story? If you're too distracted by your hate on the characters and the voice acting, you can easily miss something (at least similar things happened to me in other games). And some aspects of the the story telling rely on you to sympathize with the characters, so that would not work for you, I guess...

9 devolves into this random bullshit magic Chtulhu nonsense and 10 had very silly characters, even though Yuna is very touching and well-played. I enjoyed both games.

Oh, and Merry Christmas to me!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!11
