I'm enjoying it. My main beef is that I'm a PC gamer and I don't use controllers and I'm beyond sick of controller/console influence on game/UI design. It's easily endured for this game because the game is so slick and so insanely packed with excellent content.
I use a normal/simple mouse and rebound several keys - it's all pretty typical MMO/RPG/FPS bindings by default (which means for me they get optimized to suck less).
- movement feels like a console game - it's not precise, character feels drunk/high/uncoordinated or like you're being forced to simulate playing on a controller.
- UI overall is clearly for controllers and consoles and not for PC. As usual kb/m have to suffer thru craptastic UI design and really the ONLY screen they did up for PC is the main screen where they replace the controller diamond for abilities with a hotbar. Outside of that, it's a clickfest of multiple steps to do the most simple of tasks (like weapon mods) that would usually just be a simple drag and drop in one window for PC. I don't need a spreadsheet for every UI window but only being able to see 4-5 inventory items at once when I have a starting cap of 60 is pretty silly (is having options so bad, why no option to toggle this to be less stupid?). You can't even see all your attributes on the character screen at 1920x1080 without scrolling...it's 6 values...c'mon. It really boggles the mind. Even most blatantly screw PC console games on PC do better with some of this stuff.
- Level load times are pretty harsh but it's a graphical and huge game, and I'm sure this is yet another area where consoles hold the game back - I mean, it's pretty impressive that this game even runs on the ancient consoles. I find I'm not loading that often though, as I'd rather keep exploring whatever zone I'm in than and I don't really switch zones that often or go back to main base or even quick travel withing zones that much (yet at least). Gathering nodes respawn and wandering mobs usually do too so travelling explored ground is sometimes rewarding. So, since I'm usually obsessively playing, the loading screens once in a while aren't bad - a forced break.
At least you don't have to load every building, cave, etc. Once you're IN a zone you're set. You can look into buildings, caves, etc, walk right in, see out to the live world from within. It's a much nicer system than say (heavily modded making it worse) skyrim where you have intrusive loading every time you want to enter/leave even a trivial building or mini cave/dungeon. The size of zones and number of little bits like caves and buildings is pretty impressive and it's glorious for it all to be seamless within the zone itself.
- I've had the game lock up and crash exactly once, other than that, no real tech issues running autodetected ultra everything 1920x1080 on PC.
As many reviewers have stated, the game has some imperfections (and IMO, those will vary by player) but they're easily ignored considering the many, many things the game does gloriously well. I'm incredibly impressed and I'm not that far in since I can't stop exploring and getting distracted. I've only done one main quest step so far in 8+ hours of playing and have more exploring planned before moving to the next main step.
