The only thing close to censorship at my house for video games came a little before Christmas when I was in 6th grade.  I had Mortal Kombat for the SNES near the top of the list.  My mom set me down and said, "Do you know what Mortal Kombat means?"  I said, "Yeah, you kill the other guy."  Being the smart ass I was, I went on with my logic, "Mom, how much Duck Hunt have I played on my Nintendo?  Have I ever wanted to go duck hunting?"  I still think that is pretty sound logic.  She still likes to tell that story.  She thinks that's big league funny. 
In case you're wondering, I got Mortal Kombat that Christmas.
