I was thinking more along the lines of what Tyler said – I think it probably has more to do with accessibility of people, rather than accessibility of games.
Speaking for myself for a moment, I am perfectly “at home” at gaming events like this. I’ve been to many local Gaming conventions and even to one of the big ones (Origins) a few times. In addition to that, I’ve traveled to locations all over New England for one-day events or tournaments. I am not intimidated by walking into a big room full of strangers who game, because I know it will be easy for me to find a game to join.
I’m sure the above is true for everyone participating in this thread… But if we take a moment to consider the folks for whom this may not be true and I think having a greeter of some sort would be a good idea to help ease this people in. It wouldn’t have to be the same person for the entire day and we could probably pull them off around late afternoon when “new” attendees coming in would be less likely.
Wouldn’t have to be anything fancy – have a table by the main entrance with someone sitting there. Maybe even add a “sign-up” sheet – that would have a side benefit of giving you a more solid idea of the number of attendees.
Back on the topic of having more accessible games, I think Rod’s suggestion makes the most sense and this ties into the “greeter”. Having some of the simpler/family friendly games available and maybe recruit a small group who will be willing to run these games for newbies and if anybody who’s obviously “new” games in the greeter can direct these people to that group.
Of course, this does require a bit more organization and forethought.
