I think tabletop gaming counts as a hobby, especially if it includes deck building for collectible card games or painting miniatures for war games and role-playing games. There has been a resurgence in games over the past couple decades, and I would even argue we are in a new golden age of game design for mechanics and material components. Classics like chess continue to draw new players, too. Reading can also be a hobby, and as a librarian, I am pleased to report there are still readers of all ages.
