PUBLIC MARKS with tags rpg & history

Very few RPG series stand the test of time. Sure, a few sequels might spring up here and there over the course of a few years, but how many of them last for over a decade? I can think of a couple, like Final Fantasy, Dragon Warrior, Zelda, and perhaps a few others. These all have their charm and place in gaming history, to be sure. There is one franchise, however, that while not exactly a series per se, it has endured in one incarnation or another for almost fifteen years.
