PushSquare: "It's just typical isn't it? You wait four or so years for a great Mario Kart clone on your platform of choice and then two come along at once. Modnation Racers looks to have all the makings of a great kart racer, and then some; though we are concerned with the some of the performance issues that were apparent in the beta. Sonic & SEGA All-Stars Racing is a little less ambitious - this is purely Mario Kart with Sonic characters. And from what we've played, it feels fantastic."
