The post I responded to did not say anything about game stores.
Sorry. It said "local game community". Is that difference material to the discussion?
It intimated -- oddly -- that folks were too deluded by social media to want to do anything but the new thing. That wasn't really relevant to my initial post -- which was that despite a game being discontinued or otherwise dead, you can still play it.
You asserted one can find players. He pushed back that finding players can be difficult, because they are engaged with the new bright and shiny thing. Whether it is social media based or not is colorful, but ultimately irrelevant.
How is players being engaged in other things "not relevant" to finding players? It isn't like folks have infinite time for gaming - if they are using that time on the new shiny thing, and don't want to leave it, you can't have them at your table for an old thing, can you?
Note Being wrong about folks being engaged in other things is not the same as saying that engagement isn't relevant to the problem.
