Petric argued that Halo 3 made him insane.

17 year old Daniel Petric, of Ohio, killed his mother and wounded his father in October of 07, after they took his copy of Halo 3, is what the judge has ruled.
His defense team went for the insanity plea, which the judge rejected citing that he had been planning the shooting for weeks. He had to get his fathers key to open the lock box to his 9mm.

His father Mark, who was shot in the head and survived, testified that his son came into the room and asked: “Would you guys close your eyes? I have a surprise for you.”

He said he expected a pleasant surprise. Then his head went numb from the gunshot.

The Associated Press news agency reports that Microsoft, which owns the intellectual property for the game, declined to comment beyond a statement saying: “We are aware of the situation and it is a tragic case.”

He faces life without parole as a maximum sentence.
What do you think, what implications will this have on the gaming community if this becomes a large case with media attention?
