Gearheads of War

OK so you all know that I let my daughter play games with me.  But I watch what she sees like a hawk.  The games we play are games like Up and LittleBigPlanet.  She loves games, mind you, and she looks forward to Friday evenings with Papi because she knows it's LBP day.  She goes crazy over that stuff.

So what's my point?  I'm not trying to judge how someone else raises their kids but I can't help it.  Especially when I did venture out on XBL or PSN and hear some nine year old screaming some nasty expletives.

I was out looking at houses and we came to this one house we really liked.  It was being rented out to people who happened to be home at the time, or at least a grandmother and her grandson.  The house had a third level that was basically a small loft area.  And the grandson was probably around 7 or 8 and he was sitting there in nothing but his undies playing Saint's Row 2.  I quickly told my wife to make sure that Maya didn't go upstairs for long because I know my daughter and if she sees someone playing video games, no matter who it is, she's going to want to sit down and play with them.  We ushered her out of there as quickly as we could.

But here is my question, fellow Gearheads...what is a kid that age doing playing Saint's Row 2?  I guess maybe somewhere down the road I might understand how if your child is mature enough to handle the distinction between reality and fantasy, then maybe you consider it.  But I just have a hard time believing that this would be the case.  Am I just being a prude about this?  Or can you see it being OK for a kid that age to be playing that game?
