GameSpot (80/100): "Although the core of Sonic & Sega All-Stars Racing is obviously pulled straight out of Mario Kart, this wacky racer can stand on its own four wheels. The tight controls and excellent track design ensure that head-to-head competition is always exciting, but it's so fun just to play around with these karts that it's easy to lose hours climbing the online leaderboards in Time Trial mode."
1UP (B): "Though it has some hiccups, unexciting party modes, and a questionable difficulty curve, All-Stars Racing is a respectable effort that makes a good kart racer at its core (and is at least much more cohesive than Sega Superstars Tennis)."
Nintendo Power (8/10): "It isn't quite the fan paradise it could have been, but it's a very good racer that makes great use of classic Sega franchises. We wouldn't mind a sequel with more franchises and tracks included."
IGN: (8/10): "It's pleasantly surprising to find out that the Nintendo Wii edition – apart from the lower resolution – gets similar treatment with close to the exact same features as the stronger hardware."
