A prototype of The Simpsons Game (New-Gen) that made was before E3 2007 started.

This build has an early version of Springfield in the level Mob Rules which is vastly different compared to the final, with different road layouts and buildings like the Hospital and the Cemetery. The early version of Springfield still has a bunch of leftovers in the final game, like in the cutscenes or background models of the levels, and is also used for the Old-Gen Wii Prototype's Homer Bowling minigame.
