Reviewers mistake it as unsophisticated because it has a cartoon look and a learning curve of about 12sec.
What really shows me the true degree of sophistication and beautiful craftsmanship is that it takes a range of characters and vehicles with clearly different characteristics including carts and bikes but balances them so well that try as I might, I cannot find any combination that has a real edge over any other. That is difficult to achieve but makes for great game play.
Played with good cometitors I personally find it just as challenging as the simulation racing games and a lot more fun.
The often complained about targetting of the leader is also a well thought out device. The best driver will still always win overall, but the seemingly unfair barrage will let the weaker players win just often enough to make the game fun for them also. That way a family, for exampe, can all have fun, even when one player is clearly much stronger.
Achieving this degree of balance requires very skillful and sophisticated game design and execution and a fine polish which I personally did not see in much higher rated games such as GTA.
