Unfortunately we have decided to pass on hosting a Mega Game. Doc and I both helped out on Watch the Skies and from our experience, hosting one would be too big and complex for Castlecon. The volunteers alone would equal a 1/4 of the convention attendees and the space required would tie up one of the rooms for most of a day. There were also lots of added expenses like renting curtains to create required separations and printing out large maps and loads of documents for every person, among other costs.
I’m sorry we are unable to run the Mega game.
