It is common for licensed IPs to clone off popular game genres that were touchstones within the gaming community. The Simpsons: Hit & Run, while being a Grand Theft Auto clone, surprisingly resulted the game as being one of the best ever made, staying true to the source material and for having a unique spin on the usual formula. It's so well-regarded it even has a dedicated modding community.
There's a whole lot of content to be found within the game's files, such as unused models, graphics, music, dialogue and even traces towards scrapped levels! There's also references to earlier content that were left in last minute that can be accessed via cheats.
