I know this topic has come up before, but it bears repeating: the hobby really needs an inexpensive yet complete introductory game. Yes, yes, I know we already have several, most notably Labyrinth Lord and Swords & Wizardry. The problem with both is that neither is available in non-specialty stores and neither looks like a game to the uninitiated.
Here he goes again, blathering on about boxed sets. There's a reason I do that and it's simple: to people outside the hobby, you buy a game in a box, at least if it's a game you're going to pick up for kids to learn. I don't think it's a coincidence that the best-selling RPG products of all time have been boxed sets. I understand that producing a boxed RPG is expensive nowadays; that doesn't change the fact they're a very attractive way to package a game.
The other vital thing is getting those boxed sets out to places like Toys R Us and Wal-Mart. Having young children, I go to toy stores quite regularly and there are a lot of fantasy themed games and products out there. Lego recently started a very cool line of fantasy sets that include knights, dwarves (complete with tankards of ale!), trolls, skeletons, dragons, and wizards. How wonderful it'd be to see a RPG on the same shelves. I don't really know why D&D is no longer to be found in such places. You'd think, given the tentacles of Hasbro, that it'd be an easy matter to ensure the game was sold in them, but I haven't seen D&D outside of hobby and book stores since the 80s.
I know full well that these aren't magic bullets. They won't turn back history and return roleplaying into the fad it once was. But I'd still like to see these games accorded the same opportunities that even collectible card games are (which you can get in Toys R Us). I recall Gary Gygax musing in the pages of Dragon that, one day, Dungeons & Dragons would achieve a steady state and become like Monopoly or Clue -- a classic game each new generation could discover and play with previous ones because the game was forever in print, easily available, and largely untouched by time. I like the sound of that.
