Well, one difference between a car club and a gaming club is that car clubs don’t require you to go through huge rules manuals to be part of the action. Gaming has always required that someone on the inside stick out a hand.
I don’t know: all hobbies have their stock of arcane knowledge. And when you get into areas such as mods, advice from others is very welcome & necessary.
The big difference I can see is age. Not many children own cars, so any hostility to very young people per se is missing.
