In its current state, Rivals certainly feels quirky and looks great, but the gameplay lacks the precision of the old side-scrolling Sonic classics. End-of-level boss encounters get particularly tense, as you're tasked with defeating a giant metallic monstrosity while simultaneously keeping your enemy from doing so. Success doesn't rely solely on platforming prowess, though-you'll pick up various power-ups along the way that dynamically morph into offensive or defensive tools depending on whether you're in first or second place. Sprinting, running, and looping suddenly become far more dramatic when you're constantly trying to stay ahead of a rival. You can tackle the game solo (racing against A.I.-controlled critters), but Rivals is clearly intended for two-player action. Here, you take control of Sonic, Knuckles, Shadow, or newcomer Silver (who's also in the PS3/XB360 Sonic game) in a series of grueling one-on-one races across traditional platforming stages. Rivals hearkens back to the classic 2D sidescrolling Sonic games of yore with its basic run-and-jump gameplay: yet its striking 3D visuals and Wi-Fi multiplayer footrace gameplay couldn't be more modern. Sonic's first foray onto the PSP isn't what you might expect.
