Or the fact there is a limited number of us that own arcade hardware?
And most of us that do, know a fair bit about how it works and ask limited questions?
I'm not totally against it, but what would it encompass that couldn't be covered in all other sections? Most posts regarding arcade hardware here, tend to be supergun et al related, and are something specific like AV issues, which those respective forums encompass in general.
I guess I just wouldn't want to see a post in an arcade section with valuable information that could pertain to something non-arcade, go unnoticed because the user isn't interested in arcade machines. We all do some off the wall stuff here, that tends to yield useful information to the uninformed.
Just take a look at my first half a dozen posts or so and you'd probably get an idea of what I mean. My posts would probably have been overlooked by the more inclined users here that gave me some ideas, that aren't necessarily interested in arcade stuff. My posts being generally AV related, I got helpful generalized answers that I could apply to something besides my arcade hardware if I needed to.
