Well, if my time spent at anime-cons is any guess:
I'd bring my 3Ds and a sketchbook. I would ask fellow ZDers for their Dark Links (A Link Between Worlds), Pokemon battles, and see if there are enough Kid Icarus players to set up Light vs. Dark battles. If Super Smash Bros. for the 3Ds is out by that time, people who want to play with me would be playing lots of that with me. I could see us doing a whole lot of group-gaming.
If it were a proper con, perhaps someone would set up a theater-screen with epic gaming for people to participate in, perhaps even setting up tournaments.
If I know my fellow Roleplayers well, I bet DarkLink7, Hylian_Monolith, Tatl_Tails and I, and perhaps others... will be setting up all kinds of goofy LARPs. Come on. You know you want to see a 35 year old woman zooming around a convention hall with her arms out pretending to be a dragon or a Loftwing!
I'd take my sketchbook and doodle things for people, or perhaps sign autographs, because... um... I actually think some people (fans of my fan fictions on here) might actually want that?
I'd wear one of my pieces of bone-jewelry and would let people touch it. (I actually do this frequently in real life).
I think I might actually bring one of my crosses made of bones to just to annoy some of our more vampiric members.
Actually, it's kinda funny. I had a dream about this very topic last night...
Did I at least die honorably? Tell me I had a hero's death!!!
