I heard that Gameloft's Shrek Forever After is close to the CB games. Haven't tried it yet though, but I loved the CB games, too!
Crazy Hedgy is 3D game, but it's a ball roller, but it should definitely not be overlooked. One of the best games of 2011.
It's a bit old thread, but I'm a big fan of Crash as well and that's why I made Buster and the Crystal Bones at Buster Studios. We've tried to resemble the gameplay of Crash as closely as possible.
