Oh yeah, they're also the only arcade on the Twin Galaxies International Registry of Historic Video Game & Pinball Arcades that is still in business (the other four are shut down).
Fun Spot isn't one of them?
I can't find a full list anywhere on the internet, but the only other one I can find on the list was the Pak Mann Arcade in Pasadena, CA.
From what I remember about the award, the arcade must have been open for at least 20 years and must have been its own entity (not part of an amusement park, bar, etc). I'd assume this is why Funspot isn't on that list.
There's another guy making a list separately from Twin Galaxies (and I think Funspot is on his list), but the qualifications are far less stringent and no one actually takes the guy seriously.
