I turn my lights off when I'm not home. I'm all for entertainment, but "Gran Turismo anywhere" is unethical. Yes, It's morally wrong.
Older PS3's use about 200 watts, newer ones around 100 watts or so. "Gran Turismo anywhere" will mean thousands more PS3s on at any given time, and will be designed ONLY in an effort for patching up a botched gametype, B-spec. This really isn't a form of entertainment, it's just a way of acquiring artificial rewards without any sort of accomplishment.
...On the other hand, I think this guy just make an argument for duping and other exploits being "unethical."
Too bad it's a nearly merit-less argument.
