I can understand that, it is important to go to one of those just to see what they are like, I want to go to one someday, if I can actually make it..
I think and important thing that was missed is knowledge/trivia.
You are a casual sonic fan if you don't know who Mighty, Bean, or Sonia is, or don't know the name of the band that makes most the main themes of the Sonic games, or who had the most redesigns.
I know a fairly high amount of trivia outside of the handheld games and early archie comics, so If you would like me to throw some questions in there, let me know.
