I've worked GenCon twice, once helping ICE out a bit and running my own tournament event and once while I was working at WotC and I just don't want to run games there anymore. Have also been twice just for fun. If it wasn't 2200 miles away I would run games, but I'm more interested in playing than GMing, so I just can't justify the cost of going all the way to GenCon only to 'work'.
I'll have to see about the gaming in RM part though. However, when I got to GenCon I usually play games I want to try out or don't get to play regularly at home. RPG's that I don't know and want to see I probably won't even sign up for, but rather just show up to watch the start (intro) and a little play to see if it's something I'll like. Board games I want to try I'll take part in however as I want to actually PLAY to see if I like the strategies.
Definitely up for a meet and greet again however.
