I cannot wrap my brain around this. For boardgames, which is a growing market and has been for years now, people are buying and learning new games every day, especially geeks who are only too eager to teach them to their gaming groups.
How come for RPGs it's too difficult for one geek to evangelize a new RPG to their group, especially if they are newbies not too invested in an ongoing RPG campaign?
D&D is a very complex system, there are far simpler, newbie-friendly rules out there. How come you cannot convince your newbie friends to try one? One other commenter was mentioning how complex D&D is, how every spell and level and weapon is interconnected in very restricting ways in order to prevent overpowered characters -- that cannot be easy to teach! I played plenty of D&D based video games, like Icewind Dale, and for the life of me I'm thankful the computer hides all the complexity; I wouldn't have played them otherwise!
