Conclusion: In the end, Pac-Man World Rally simply has nothing unique, special, or fun about it. It's a serviceable training-wheels rendition of a kart racer for that younger audience, but for anybody looking for more than a quickly beaten game, look elsewhere.
Pros: Power-pill mechanic is amusing, lots of characters and courses to choose from.
Cons: Difficulty level hovers somewhere around zero, most of the game mechanics are directly lifted from other, better kart racers, secondary modes aren't much fun, standard frame rate is exceedingly low.
Conclusion: It is not so much that the development of Pac-Man World Rally was necessarily bad, it was just that the end result could have been much more original than what we were given. For all those wanting another chance to relive the good old days and try Pac-Man out on his new wheels, then you may want to rent this game. Otherwise I would say stick with the many other great Kart racing games already on the market.
