Hey, all. I'm going to GenCon this year, and thankfully my visit is longer than 1 day this time around (which means I can attend events rather than just troll the exhibit hall).
Now, I'm an old-school SR veteran from the 2nd ed. days, but I lost my group back in the post-high-school/college shuffle and haven't been able to really get back in the game since, especially since I work weird hours. However, I've still kept up on the game as much as one can w/o actually playing -- I have SR20A, all of the other core books, and most of the other SR books CGL has published (JMH even signed my
6th World Almanac @ GenCon last year!

), but I'm not sure how confident I'd actually be in playing any of the Missions events at GenCon.
A few questions:
--Would knowing about the game world be enough experience to join in even I'm not 100% up-to-snuff on all of the SR20A rules?
--If I do sign up for an event, do I need to have a character created beforehand, or is a character sheet simply given to me?
