Think of it this way, a few years ago I had stopped playing blockheads due to my world being deleted after changing phones. I started again a few months ago, go into the new update and currently now a regular on the forum, which I had never done before. And help players online.
Even with new games, I got a simulator that lets me play old games like, Mario, snake, bounce and space impact.
Pretty sure as long as the game has been enjoyed by people, there will be those that come back to it and playa again.
