I honestly don't really understand what his videos are about. I mean I know they're supposed to teach people about cultural influences in games, but I just don't understand what he's going for, if that makes sense. Most of the things he covers are fairly blatant and well known, or are a complete shot in the dark when it comes to connecting them to the game. I guess I can appreciate the information but really I just don't see the appeal of making a whole video pointing out references in games.
There's a lot of people on the internet that get a kick out of just having their personal interests noted or validated, especially in gaming or anime social circles. You could argue it's why in-jokes exist. Reference humour in general has also made up a lot of peoples' comedy tastes over the past ten, fifteen years. See: Family Guy and South Park.
