Some games tend themselves. They'll be around no matter how much time passes and they need no one to attend to their memory.
However, some games are an endangered species. They sit on the precariously on precipice of popular culture threatened to plunge into oblivion and be forgotten forever.
That is why we often, with a certain sense of urgency, try to ignite a flame for our old favorites in new players, so that should one torch be extinguished it will not be forced to go gently into the night.
And it never works.
