There were plans to add downloadable content to the game, but was ultimately scrapped. According to producer Hans ten Cate, the plans were aborted because of the late 2007 Writers Guild of America strike, and because EA Redwood Shores shifted focus to other projects. One idea was DLC expansions for the Springfield hub world, and there are still leftover textures for this in the game files, though it's unknown what these areas would have actually contained since all the textures are placeholders. Another idea was DLC character skins for all the main characters. A significant amount of artwork was created for this, including designs based on different regions and ethnic variations, leading up to the game's ending scene. This DLC was also developed alongside the production of the 2006 film "The Simpsons Movie".
