To address this, EA's street-racing title, Need for Speed Underground Rivals, is set in an entirely new city. It comes with a range of muscle cars that are unique to the PSP and features drag-racing and drift-racing modes that provide short bursts of gameplay for people on the gowithout sacrificing any of the car-customization options that helped make the first game a hit. Similarly, Activision's skateboarding game, Tony Hawk's Underground 2, comes with four brand-new levels to go along with the 15 from the PS2 version. You can store a picture of yourself on a Memory Stick Duo to play as yourself in the game, and the three-minute time limits in classic mode can be squeezed into even the busiest schedule. And both games support Wi-Fi, with two-player for EA's game and four-player for Activision's.
