I think it was best said by FrankMentzer at the end of the Gen Con auctions last year. Introduce young people, a friend, a neighbor and there children to the fun that is Gaming, or else one day it will not be there.
I personally believe that when 25,000 or so people are willing to make the journey to Indianapolis for Gen Con, that the industry is not in any pain. I know for certain that when I go to Gen Con I am buying for four other people who could not have made the trip but want all the cool things that are newly released. So if I am buying for 4, how many others are doing the same?
The one thing about this hobby that seems to have its downfall, is the requirement to have social interaction in person. Interaction nowadays is so easy when you turn on your computer and there the world is just setting there waiting for you without the need for face to face, but going out and making friends in person can be a bit of a nightmare, and the fact that scheduling a game for those of us who have fulltime jobs and families to go home to can kind of be tiresome if something falls through and things need to be rescheduled.
I do know that Palladium Games tryed to go under, but there fanbase put together 100k in less then two weeks to bring them up and out. So the industry as a whole still must have some money in its veins.
