According to this article Rockstar Games' objections to the 'Grand Theft Scratchy: Blood Island' part of Electronic Arts' upcoming Simpsons game (reported earlier) go beyond some people complaining about a poster at the Games Convention in Leipzig.
The satirical reference to GTA is apparently not even a game you play:
"The game begins with Bart wanting to play a game called Grand Theft Scratchy. Of course this is a parody of Grand Theft Auto. And Marge immediately takes it away from him. She tries to clean up the town and stop the game from being distributed in Springfield because Marge is against video game violence. She uses horrific violence to stop video game violence... in a video game… That's called irony."Now this fictional game has been renamed 'Mob Rules'.
I am baffled by the reaction from Rockstar Games, and disappointed by the quick cave-in by Electronic Arts' lawyers.
