I've played at quite a few "Official Events" of SJGames, Munchkin in particular.
Coincidentally, I'll be attending the Halloween Munchkin Event at
7th Dimension Games in Jenkintown, PA this Saturday.
I will say, the insistence on a MIB at these games, has made them run much more smoothly, than other "Organized" play that I've witnessed.
MtG benefited from this as well.
High Five to
Josh. See you Saturday.
