Thusfar the response has been enthusiastically positive. I won't name names right now, because nothing is graven in granite, but it could wind up being quite an interesting event.
I've also been in touch with the fine folks who run the Dexcon convention, held each year in Morristown, NJ, and this year to be held over the July Fourth weekend. They're more than happy to let an OSR convention piggyback on their own convention as a sort of convention-within-a-convention, with the possibility of spinning it off to its own independent thing down the road if there's enough response.
The chief feature of the convention, of course, would be the games. Having a whole track of old school type games would be the big draw, from my point of view. Not having to travel to Wisconsin or Texas would be an added bonus (with no offense intended towards Garycon or NTexasRPGCon, of course!).
So the questions for the hall are, would this be something you'd be interested in seeing? Do you think the OSR can stand another dedicated convention, specifically geared towards us East Coast types? What sorts of games would you like to see represented? Just RPGs, or some old-school wargames and miniatures as well? (Like the really cool Chainmail games that some folks have been running in the last couple of years.) I've run events myself at this con and others, and invited other DMs to do so as well, but this would have more of a self-identity, and a dedicated track on the schedule.
At this point, I'm still gauging interest, but if it looks like we could hit a threshold of activity, we could see a dedicated OSR track at Dexcon this year, with an independent con in 2015 if it works out well enough.
What do you say? Sound interesting? Have some ideas? Let's hear your thoughts in the comments.
