I think there's also a spot for board games as a social outlet that requires less commitment than D&D and is more accessible than videogaming; several years ago I used to get together with friends and bring videogame consoles, more recently it's board games (and they're super easy to play with new acquaintances too). I hate to say it but games like Cards against Humanity are, in a way, the Minecraft of board games; it starts with "party" games and before you know it you're playing BSG :)
