I really like this game as something to just mess around with my family. I never really saw it as a game to start and finish quickly. Mostly because to unlock characters and places, you have to do well each time you play, and the easiest way to do that is to do the first level every time. That might not make sense, but if you play the game it will. It just means that if you're someone who has to complete a game as fast as possible, you probably won't end up seeing much of the game, you'll just stick to the areas you can do the best.
But Simpsons Hit & Run is quite a big game, and if you love the programme you will love the game, because all the characters are there, and all the places too. Even obscure references that have only been in one episode. I would definitely recommend this GameCube game as something just to entertain your kids for the odd afternoon, not a straightforward start-to-finish game.

Simpsons: Hit and Run is good to start off with but then it gets boring after finding all the cards and wasps. This is not a game to buy it is one to rent.
