Two things here:
Unsurprisingly, because why should Square Enix comprehend to any degree whatsoever the markets they are selling to especially when it comes to the Western PC gaming market, FFXIII for PC is not optimized by any definition of the word. The port itself is locked to 720p 30 fps, and the only way around this is to use Durante’s SweetFX-esque shader modifer to force override the locked resolution to 1920×1080 or whatever you want. You could also downsample and customize all of the graphics options which Square Enix did not include, at all, in the game.
Even so, and ignoring that Durante’s plugin is an early alpha build he spat out in a day, the game still runs terribly at 1080p unless you are already using a beastly GTX 980 and the latest-gen i7s. At 1080p with graphics truly set to low, the game looks good – but also runs horrendously. It’s certainly not unplayable, but pretty much defeats the purpose of gaming on PC when you could buy an xbox for 50 dollars and pick this game up for about 5, and “enjoy” basically the same experience.
Did I mention the 20 or 30gb of uncompressed cutscene videos you are forced to download just in case you want to listen to the Japanese audio? How about the fact that literally every time you launch the game, you have to customize the “options” – such as the on screen button displays – or they won’t work? Don’t worry though. Even if you do change the button descriptions to “controller”, it will still show keyboard keys and not 360 buttons or even Playstation buttons.
Oh, by the way, if you have terrible internet – do not use Steam cloud. In fact, don’t use Steam cloud for this game. If you do, the game will ONLY save to the cloud and will not create a local copy. As soon as you go offline or you turn off cloud sync, your save will be inaccessible.
FFXIII is hands down the worst final fantasy game ever made. There are those who dispute this, and good for them, but it’s not opinion. The combat system is drastically hands-off in comparison to even FF12 which literally played the game for you, and to make that better, it suffers from asinine mechanics that never should have made it past quality testing. Specifically, if your party leader dies, it’s game over immediately. They fixed this in 13-2 obviously but, this isn’t 13-2, is it? Once you get waist deep in the game, though, the combat and the paradigm shift system are fully realized – but they never make for an interesting battle except for a few select boss encounters.
The voice acting is hard to deal with, in English anyway. Hopefully everyone knew that already but you have some of those PC master race kids on here who only game on PC. Vanille’s VA is schizophrenic at the best of times, and really the only voice acting you can deal with is Snow.
It’s somewhat of a shame, though, as the game does have impressive graphics and a decent story. You’ll just have to deal with a cavalcade of bullshit until you can actually enjoy the game – which will happen literally at Chapter 11 or so. Until then, you will be forced to use subsets of all available characters as they journey in separate groups around Cocoon and Pulse. For the first chapter, you can’t even level up or change your roles.
The crystarium is a cruel joke and all it does is make you hate it for not being the sphere grid. Again, they kind of fixed this in 13-2 and LR, too late though. So, more pure linearity to enjoy. The entire game is one long hallway until you get to a room – Gran Pulse Archlyte Steppes – and even so that “room” isn’t exactly the most expansive free roaming area. All of this culminates in literally the easiest last boss I can remember in any RPG.
Unless you didn’t suffer through this game the first time, or you’re a collector – don’t even bother.
