Maplestory 2 was also a sequel to an insanely successful classic MMO Action RPG that launched two years after PSO2 and now two years after the NA release, three after the Japanese release and five after its initial Korean release, in spite of the original Maplestory still puttering along in spite of it's tiny playerbase (at least on the NA servers, not sure about the rest), the GMS2 and JMS2 servers are being shut down, leaving only the original Korean release.
