... None of them were table-top players. I have met couple people who played table-top - they didn't play cRPGs.
That's pretty much the case with us and the couple we're friendly with over the road. I play lots of video game RPGs, they love tabletop, but neither of us has shown any interest in the other's preferred gaming medium. Then there's the gf who doesn't play either but is showing more inclination to join them!
