Jack Thompson, the anti-GTA lawyer, has fumed at the production of the "murder simulator" GTA IV in a letter sent to the MUM of Rockstar boss Strauss Zelnick.
Thompson suggested that she should be "ashamed of herself" in the letter, which has been reported on in the Metro.
"The pornography and violence that your son traffics in is the kind of stuff that most mothers would be ashamed to see their son putting into the hands of other mothers' children," he ranted.
"Maybe you, Mrs Zelnick, were so taken by your handsome son that you spared the rod and spoiled the child. That would explain why he has brought you, by the way he presently acts, to shame."
He goes on to claim that experts hold GTA and Strauss' "entrepreneurial energy", in part, responsible for a "plethora of cop killings".
It gets better: "Your son, this very moment, is doing everything he possibly can to sell as many copies of GTA IV to teen boys. If you trained up Strauss to do this, then shame on you," he said.
We'd love to have been in Mrs Zelnick's 'How to Sell a Murder Simulator' classes.
"What you will see in your son's game," he added, "if this iteration is anything like its predecessors, is incredible interactive violence aimed at police offers (whom you can shoot in the head and see the blood spray), innocent bystanders (whom you can run over with your car just for the heck of it)."
Then he tries pulling on the heart strings. "Happy Mothers' Day, Mrs Zelnick, which this year is May 11, two weeks after your son unleashes porn and violence upon other mothers' boys. I'm sure you're very proud."
I'm sure that'll get her to stop the sale of GTA IV.
"Son, can you not sell that multi-billion dollar game? Go on, for your old dear."
