Some people flaunt everything, some people have a lot but are humble and keep to themselves.
You could probably tell who likes to show off their collection on here, IE buy a game and show your entire full collection off when you get the one pin in, some get one pin in and only show that.. and don't want to show anything else.
I don't really like to show my stuff off, but I don't mind those that do.. people are people. What really matters is if they are cool enough to let me come over and play their machines.
