Truly a shame...
Graphics - Great. Well, I mean as far as one could expect from a game revolving around a cartoon. The world looks precisely like a Simpsons episode.
Audio - All the actual voice talent from the show is here and they do a very good job bringing the show to life in the game.
Story - Well, not much of one. It's basically episodic missions as you would expect. The writing is good and there are a few good laughs to be had.
So you're asking "'Elf, what's the problem? Everything sounds OK so far, why the low score?" Allow me to drop the bomb...
KABOOM!!!!
Gameplay - Absolutely, utterly, completely, and totally BROKEN! There is bad camera (Ninja Gaiden Black or Conan for example) and then there is a disaster of camera that is spectacular in proportion. The Simpsons Game falls in the latter category. Want clean, accurate jumping? Good luck. Want to move smoothly through the environment? Fat chance. Want to clearly see what the hell you're supposed to do next? Hah! I am in awe that this was allowed to be shipped with the camera in this state. The amount of money it must have cost to bring in all the voice actors must have broken the bank because the controls and camera were simply disregarded.
Worse still is the need to switch between characters to accomplish in game progress. Dreadful. Amidst all of this chaos you are expected to jump between characters and experience their own brand of controller related failure. And the time trials? Don't get me started. The first of course is way too easy, then absurdity ensues. Trying to utilize these controls under time pressure is an exercise in futility. Sure, you'll get it eventually but isn't the point to be having fun, not a coronary?
This game is a rental or a bargain bin buy at best. If you pay the full $60 for this game then you deserve the misery of trying to get through it.
