A mediocre game with a boosted score only by the Simpsons usual humour.
Each character (sixteen in total, each voiced by the real actor) has four moves excluding jumping. When the wrestler performs special moves their energy bar drops and then slowly refills over time when they are not attacking someone. The amount of energy that gets used up depends on what move is used. A downside in the wrestling is that some characters can win any match by repeatedly using the same move over and over that requires hardly any energy.
To become invincible your character will have to collect letters that float around the ring which will then allow you to beat the living daylights out of your opponent with no worries of having the same thing happening to you. The same rules apply as they do in wrestling - a match ends when someone gets pinned onto the floor to the count of three.
Although it sounds pretty good so far, the graphics aren't the best thing in the world. It may have the excuse of matching the style of the show, but it doesn't even do that. The wrestling is actually very repetitive and the game has nothing special in it that makes it stand out.
This is one of those Simpsons games that you can just look over. If you are a big Simpsons fan you may get a kick out of the quotes and seeing your favourite characters wrestling, but it will soon get repetitive and boring.
