Visually, Speed Kings looks good, even though a few individual elements--like some of the environmental textures and the game's vehicle models--aren't the greatest ever created. These flaws are easily overlooked, though, since you'll spend most of your time riding too fast to get a close look at anything. The sense of speed conveyed in Speed Kings is fantastic, and the game uses a blur effect when you kick in your boost that definitely gives you the impression that you're going way faster than you should be. It's worth mentioning that the game's frame rate hiccups a bit on every platform when there are a lot of vehicles involved in an accident, but it's usually a pretty minor skip. The Xbox version looks sharper than the other two versions, and makes better use of particle effects, as well.
Fans of DVD-style extras will enjoy the game's bonus materials.
In the audio department, Speed Kings has a decent array of sound effects and music. The engine sounds, crashes, and tire squeals are all appropriate. The music in Speed Kings is surprisingly low-key, but this prevents it from becoming a distraction and actually helps you focus on the tracks.
In the end, even though Speed Kings doesn't stray very far from the Burnout 2 formula, it's a solid racer that does a great job of conveying an insanely fast sense of speed and requires you to think and react in an instant. The game's controls, presentation, and gameplay modes offer enough depth and variety to warrant a purchase for fans of arcade racing.
