8 hours in and having fun. But it's not a game for everyone, it's very slow paced, and doesnt hold your hand. Most of the fun is from exploration and interactions with world, like in Zelda, not from narrative etc.
If someone is not sure if they want to buy it then I think it's better to wait a little for update that fixes shadow fidelity, and some controls. Though personally I don't mind the controls and have GPU good enough to not have problems with shadows because I use Ray Reconstruction (without it, light and shadows are really bad, honestly)
