I am a few tens of hours in. This has been one of those games where you on the one hand don't want to believe the hype, and on the other you hope that a dev group which has earned its trust over the years will actually, to use a sports metaphor, hit a home run out of the park.
There are glitches. I've had a horse get stuck in a stable roof. I've had funny endless loop characters running half inside of walls. I've had frame-rate drops, and a couple of hard crashes. But it doesn't matter. Because the game is so good that you don't want to feel ill will toward the developers. Really.
I've always liked CD Project Red. They've always gone against the grain. For instance, just by trying to push a dense and complicated Slavic-based fantasy world onto a world accustomed to low-calorie minimum-impact risk-free content for adolescent boys. Like, when you set a game like Skyrim or Dragon Age Inquisition next to this, it feels like those other games are like cotton candy next to a hearty meal.
Sometimes you don't know what you've missed until you get it. Sometimes you don't know that you'll have an unforgettable meal until you've already eaten it. Sometimes you'll walk into a dingy diner in the middle of nowhere and have the best evening in a decade.
Hyperbole? Perhaps. I don't know. There are glitches. There are issues. There are annoying details. But for the first time I've ever played a computer game, I know I've been to a world, and not to a pretty looking set that's there for the Hero to play his act of tragedy or drama. It is a world; feels like a world, and it feels like it's a world with people. That kind of forgives all the other technical stuff that's bound to crop up in a huge thing like this one.
I'm not sure it is for everyone. I won't pretend that it's for everyone. I just know that this one is for me, and I'll expect to explore every inch of this world. God damn, this is an awesome game.
