I guess the irony is that the guy violently killed the people to get the game system with violent games. Why do people kill each other? The only other animals that do that are cannibals or it's some dominance thing. I mean, for the most intelligent beings on the planet, you think we'd get over killing each other, especially for some hunk of metal and plastic(I'm not even sure if we are the most intelligent beings on the planet).
I wish I was in the forest with a dragon right now.
