"Quake IV also benefits from a color palette that strays beyond the shades of brown and gray featured in the early games. Like Doom 3, there's plenty of mighty fine texture work on display. Behind the scenes, the game makes the most of modern high-spec graphics hardware to give an impressive depth and presence to even the most mundane and ordinary of objects. While it's not as photorealistic as Half-Life 2, the world it creates is almost as convincing."
