Not to sound totally pessimistic on what Ryan said, but do you honestly think he would actually report that the number of gamers is shrinking vs. saying its growing? I don't think so.
The reason why I say what I say is because I have known many people around here who are leaving the hobby because of whatever reasons, and I am sure we are getting new people all the time but it might be equal. Then again, what he says might be true, but he has to say what he said in order to make it sound as if things are going as they want, and I don't think things are going as peachy keen as they want them to be, but they are going just good enough to keep it going.
What I am wondering is what things could we do, either as gamers or as companies that produce rpg games, to get new people into the hobby?
It would be nice if each FLGS would go out of their way to try and run demo's for kids after school, but we all know that they cater to card games more and most LGS's are just fine with that. Speaking from experience, all the employees at my LGS don't care about rpgs and none of them play them, so they never promote them. Then I hear them complaining about the lack of rpg sells, and this is now why they are now ordering only d20 stuff, and a few non d20 products.
If your happy with just saying that things are fine and there is no need to try to get more people into the hobby, that's fine...but at the rate things are going we will see the same people playing the games (maybe a few people will be lucky enough to live in a location where others are actually willing to show up to see a rpg game but most are not so lucky) and no mass fresh newbies coming in.
If there needs to be any new point, the average age of gamers has steadily increased over the last 20 years, as most of you on these boards have been gaming for at least over 10 years, if not 20, and the numbers of new gamers is not as high as they report. IMO of course.
