The Simpsons Game is an action platformer for the Wii, PS2, PS3, Xbox 360, PSP and Nintendo DS (each platform has its own exclusive box art design). The game features locales and characters commonly featured in the Simpsons TV series. The game follows Bart as he finds a manual to "The Simpsons Game" and, with it, gains video game like powers for not only him, but his entire family. The Simpsons family then proceeds to spoof several popular video games, such as EverQuest, Call of Duty /Medal Of Honor and Grand Theft Auto.
The game play is very similar to the Lego platforming game series, with similar features such as its inclusion of drop in, drop out co-operative play.
The game also features voice overs from all of the cast of the TV series, each reprising their roles as their respective characters.
