Some first impressions from my first hour of playtime regarding the port and comparability to Hyperdimension Neptunia:

First off, the game runs smooth even on my old toaster card. This is likely due to it being more CPU intensive to begin with, but even then I am seeing no hiccups with my i5-4460 and my HD5750, running Windows 10 Pro x64 - in other words, the game runs smoothly at 60fps (which is the default lock as per the .ini file, but may be unlockable).
There are no in-game graphics options to speak of besides resolution and a fullscreen/windowed/borderless toggle, but then you'll hardly need more, seeing the game's artstyle and heavy reliance on animated 2D backgrounds and sprites. Further graphics settings may be available in the .ini file again, and AA can be forced via your graphics vendor's control panel regardless.
Settings for controls, sound and so on are all there, including manual button remapping for your gamepad (which should help with getting non-standard Xinput pads to work), and Voice, Movie, Effects and BGM volumes have separate sliders, as they should have.

From a gameplay standpoint, the game is close to Hyperdimension Neptunia Re;Birth, which it supposedly shares the engine with. If you've played Neptunia, you'll find it easy to get into the systems, though even after an hour of playtime, there are differences and additions in Fairy Fencer F.

Those differences include the Tension meter that raises/lowers your stats in combat and allows you to transform at a certain point (whereas Neptunia gave you more free reign with transformations), "boosting" weapon stats, learning new skills and what not through using them to earn and assign points, attaching Fairies to your characters for added perks, switching weapon styles to increase certain parameters like crit chance, speed and the likes, and Character Challenges which reward you with stat increases for various gameplay milestones.
These challenges also encourage cycling through your party members, as some of them demand a character to be the party leader or do things only the leader is able to. It is a nifty system I'm looking forward to explore more in-depth, as it should keep things fresh (if a little grindy in the higher ranks, I expect).
Overall, the gameplay system at least feels more complex in terms of customization and late-game options than Neptunia (though take my judgement with a grain of salt - I'm not that far in yet).

The story and characters up to now seem like a good combination. The character dynamic between the protagonist and his fairy partner are funny and lighthearted, which reminds of Neptunia, but appears far more grounded and less preposterous than Nep did. If Gamindustri felt too wacky and over the top to you, Fairy Fencer F might deliver a more enjoyable experience.
The basic plot is very simple in theory: Collect all the Fury weapons and revive the Goddess, explore dungeons, talk to people in towns (again, more grounded than in Neptunia, though very similar in execution), and fill your protagonist's stomach.

The art design and music are straight-up gorgeous, as would be expected from the team behind them (which includes Nobuo Uematsu as composer and Yoshitaka Amano on the art, two big creatives that made Final Fantasy so good in its glory days). Fairy Fencer F offers some top-notch, high quality art in the typical J-RPG/Anime style.

Overall, I am pleased with my purchase, and will continue playing it.
