I don't think there is a public resurgence but there is growth in the hobby. The internet started it with access to information about pins, where they are for sale, and tech help. That made buying and fixing games easier for more people. That caused others to start small businesses catering to the needs of hobbyists. That led to more people being able to fix games reasonably easily and so on...

...as the hobby grew, new people brought in more money and demand rose for older games which caused more people to buy new games as the prices between used and new got closer...
