Well that last line certainly has thompsonesque overtones (foreshadowing perhaps) but I'd say the real danger was that his girl's parents didn't nip this **** in the bud before it got out of control but they probably didn't know about it. I mean the girl obviously TOLD the guy where she lived, that's how he knew where to send the gifts/himself. He had her text messaging id, she seems to have accepted multiple gifts without ever telling him to stop, she told him details of her life such as her ahving a sister. Seems to me she was leading him on and them she developed cold feet once he actually arrived. Not that it's not creepy as hell for a grown man to be chasing a minor.
The problem is that, despite the fact that this is a "Mature" rated game, and that parents should be monitoring their children's online activities, I predict that there will be an outcry about online gaming. Honestly, I'm surprised that it hasn't come about yet. You almost can't go into a Halo or COD4 game without having a few underage kids in there.
We all know that there are plenty of creeps like this guy online, looking for kids to prey on. Whether it's Xbox Live, PSN, Myspace, AOL, doesn't make a difference - anywhere that you have adults and children interacting, you're going to run into this sort of behavior. We know that the best solution is for parental involvement - watching what your kids are playing (and who they're playing with), using the parental controls that exist on the consoles, etc. But I'm afraid that we're going to see some sort of demand that Microsoft, Sony, and Nintendo take steps to insure that their online services are "safe".
