Gamasutra - Can Games Become 'Virtual Murder?'.
If, in this hypothetical future, we're capable of stripping away our empathy and compassion to murder a 99% realistic virtual human (and maybe even enjoy it), will we be psychologically any different from people who actually murder those of flesh and blood? Having perhaps unintentionally trained ourselves to become cold-blooded killers through systematic desensitization, will we be emotionally capable of doing the same thing in waking life?

IncGamers - WoW is Killing itself. Thanks Ant.
Yeah, that's right, you heard me. WoW is in the act of committing suicide, and Blizzard don't even know it. Now, before you get all huffy and angry with me (save that for later, you Blizzlovers, you), allow me to give you a bit of background. And when I say background, I mean way, waaaaay back, to the games that inspired WoW in the first place, and to where these games went wrong.
