There ya go...duct tape him to a computer chair, toothpick his eyes open so they can't shut, and make him watch you play for several hours. If that doesn't work...we are left with a VATS head shot to put him out of his misery.

I have such a friend too. He is quite honest about this and says he is easily disturbed by Fallout 3's bleak environment and dark dungeons. "All right", I say, "I understand your opinion. Just wondered if you could give it a thought".
It's none of my business what he plays, even if I would prefer if he did play Fallout 3.

I have a mate that trys to pretend he likes FO3, but I know hes faking it.
