To be fair this thread is not 6 months old yet. Anyway the main YouTube channel I watch is KYRSP33DY. It is a gaming channel, but I will say that it isn't really family friendly only because of some occasional language. The only videos I watch of his are of the videos of games I myself enjoy playing. I enjoy watching his videos because I find them very entertaining, and on a side note he is a good video editor.
I really enjoy watching Bored Shorts. They call themselves Family-Friendly Comedy for All Ages. Although they're not gaming-related, they're quite enjoyable. I especially recommend watching some of their Kid Snippets.
