No matter how big, it’s not impossible to fall from the public eye. While Saber Rider was very much niche, the western itself has disappeared. I can’t think of any genre more identified with the American experience that has fallen in prominence so much. It might be wise for MMO designers to remember that nothing is guaranteed. Even WoW may be as much of a history lesson and a fad for a generation as Gene Autry or Roy Rogers were.
