But that is not the whole demographic of 10 to 20 year old boys Even if they are looking for a Sims video, children might reconsider watching your video if it says 'family friendly' in the title, just because they connect 'family friendly' to 'things for (young) children'. It's all about their frame of reference.
I wasn't focusing on boys though. I was focusing on children in general. That includes girls. If we are talking about frame of reference, then it would be pretty likely that girls would have less issues with family friendly content. You are right though, it all comes down to what audience you want to reach.
