It saddens me to have to give this game a review poorer than I had hoped and anticipated but in fairness, they left me no choice. I will point out some pros and cons and let you decide for yourself where this game is worth getting right now, or you'd rather wait for CDProjekt to finish it. (not fix, truly finish)
CDProjekt made a beautiful game, for it is stunning not just fidelity but the sheer artistic set pieces are jaw-dropping at times. From the simple things as beautifully thematic bridges rich with details to gawk at to rides, you're going to want to steal immediately. Even on the lowest settings, this game looks, beautiful.
The characters as one can and should expect from these developers are fun, rich, and have a depth to them that makes you want to know more about them. The writing is good, like really good. In some instances, your actions have unforeseen consequences which they should foreshadow better but in all the writing is solid, fun and whimsical. You will get attached, as you did in the Witcher games. I hope they carry that over into perhaps a trilogy or simply more material for us to bond with these or other characters over years, not just a single game.
The combat is surprisingly good, you have many options and it's not nearly as clunky as I expected since the Witcher didn't have great combat, it was overly simplistic, and it was a whole different genre of it. They did well, you are unlikely to get bored of it any time soon.
That's all I will say about the pros, and I don't wish to spoil the story or any events or even features you might encounter. I will only talk globally about these things.
Now I do have to address why this game is not a five star, something I would have loved to give them and the game.
It's a mess...
There's no other way to put it. It's unrealistically buggy and it breaks immersion because of it, some are silly, some are breaking. But I have hopes they fix that.
It misses features, a lot.
It doesn't run well.
