At the time of release the developers, Capcom and Nintendo were accused by fans of copying the tactics of the Pokémon games by bringing out 2 similar games at the same time to increase profits.
Unlike the Pokémon franchise, however, the differences in the two Zelda titles are extremely profound. Oracle of Seasons is more of an action-based game, while Oracle of Ages is more of a puzzle-based game.
The Triforce has teleported Link to Holodrum, a troubled land. He meets a travelling troupe of dancers, the leader, Din, actually being the Oracle of Seasons. Suddenly, an armored behemoth named Onox appears and teleports Din away. The seasons in Holodrum change at a moment's notice now, and it is up to Link to find and upgrade the Rod of Seasons and rescue Din.
