The system requirements are fairly steep but you can turn off a lot of options. I love the shadows that follow the characters and monsters. One of these days I'll try turning up all the options but it looks so good now I haven't bothered. Day and night cycle which changes the look dramatically and also affects strategy. All in all the graphics are awesome.
Music is very nice and soothing, changing to dramatic-sounding when combat begins.
The atmospheric sounds of birds, rain, thunder, etc. are all well done. People knock the main characters' vocals but they seem ok. Give it a chance and you will really like it. Gameplay is fun and really makes you think. There is tons of gameplay here.
