Gaming doesn't have to be competitive, of course... I'm mainly thinking of RPGs here. But then, there may be the trepidation involved in knowing perhaps more complex rules. (Lots of RPGs have incredibly simple rules, but not everyone knows that.)

Do you do gaming? I seem to remember that you do, but my memory's not great.

And by the way, I wasn't checking up on you -- you seem like a genuinely cool person! I'm serious about trying to share a meal at a con sometime.
