Tabletop games, and any activity where you meet with a small group of regulars, is resistant to the perils of popularity. More people playing D&D means the publisher can publish more books and offer accessories, because they're confident there's a market. But my core playgroup hasn't changed much for years. We meet new people at open events, and if we like then, we'll invite them to join our regular group. It's naturally resistant to mainstream dilution. More so because it's a game where we write the narrative, choose the themes, and freely change the rules.
