MapleStory is a universe that was created for a free-to-play MMORPG and that has since been adapted to an RPG for the Nintendo DS. The games are set in Maple World: a vast realm comprised of four continents (Maple Island, Victoria Island, Ossyria, and Masteria).
In the MMO, Maple Island is the beginner-friendly starting region, while Victoria Island is the early gameplay region where the players upgrade to their first job. Ossyria holds many of the game environments, with seven distinct regions. Masteria is a new continent that currently only contains three cities.
The MapleStory games have players control heroes that adventure and gain power by defeating monsters and completing quests.
