Didn't like it. Certainly not as much as I've heard others liked it.
Not that it was bad, just didn't think it was what everyone else was telling me it was: "The best RPG you will ever play!" Every review, professional or otherwise, seemed to give this impression that it is the best of the best as it were. The odd bit is how most of what people said was what made it great didn't in my eyes. Again, nothing was really poorly done, but neither did much of it seem spectacular. I feel it's way over-hyped and exaggerated.
Did like some of the supporting characters, though, which wound up being probably the best thing about it to me...that whole plot line with the Baron and trying to help him find his wife and kid I actually really enjoyed. Finding out what happened to him at the end really hit me...it was like watching a really beloved character go out in Game of Thrones or something. He was actually an enjoyable character. I felt like there were a lot of places where there were no great or graceful endings to different legs of the story, but I never felt like too bummed out by the choices I made. They all obviously have consequences that are less than desirable, but the costs aren't overwhelming or unfair. There were many times playing it where I'd see the eventual conclusion to something I choose earlier in game and think, "Well, that sucks," but it never really felt too discouraged by it. Most of those times, I'd either see that I couldn't have really known it would wind up like that and perhaps could have at least been much worse, which made such events feel more believable in a way, or I'd see what good it did at least do somehow.
Flip side of the same coin: the combat, what many told me was great, was more frustratingly touchy and oddly (missed-) balanced and the whole sign magic wound up being largely irreverent, gimmicky, and forgettable at best. I know it's the 3rd game and not the first, but the game never really properly explains why they work and even worse yet they fail to really give you the kind of edge in battle they probably should. They seemed more useful removing obstacles or lighting torches on the walls than giving you a leg up in battle. And never in any other game, much less RPGs, have I ever been more angered or frustrated with character movement as trying to control Gerralt. Being unable to actually manipulate an actionable part of the environment despite the UI giving you a button prompt to do so while Gerralt is still physically in motion is...well, it's honestly infuriating after the first ten minutes of gameplay. If you've played it, you'll know what I'm talking about. Also, fuck that Witcher Sense sight bullshit. It's ironically terribly short-sighted (you have to be pretty close to pick up traces of things) and constantly glitchy where you might not see anything at all. At least the fish-eye lens effect can be turned off.
Sorry for being off topic, btw.
