Not only Dungeons and Dragons, board games are making huge waves around the world. As a game store owner, I have observed a huge growth in tabletop games, including board games. So it's probably not a coincidence that the most highly rated board game (at least according to Board Game Geek) is an RPG based board game. At the time of its kickstarter, I think it raised the most money as well.

Speaking of kickstarter, I believe some of its most funded ideas were board games.
