Speeding down an airport runway in a shiny red sports car is cool; speeding down an airport runway with an out-of-control aircraft thundering toward you is insane. That's the idea behind Split/Second, an arcade racer in which you wreck your opponents by triggering destructive hot spots scattered all about the track. The frequent explosions, tumbling debris, and resulting tug-of-war among racers are undeniably stimulating, at least for a while. You'll whoop for joy when you demolish four opponents at once as they pass under a fuel station and moan aloud when a falling concrete beam crushes your vehicle like a beer can. These jolts are electrifying, but they aren't lasting ones. Once you learn the tracks and the tricks, the excitement dies away.
