Golden Sun: The Lost Age Nintendo Switch handheld gameplay. The Lost Age follows the same traditional role-playing video game formula as Golden Sun. Players control a cast of characters as they journey through a fantasy-themed world, interact with other characters, battle monsters, acquire magic spells and equipment, and take part in a building, predefined narrative. While many actions the player takes are compulsory and central to the story, The Lost Age allows them to complete many objectives in the order they choose. As well, visiting previous locations to advance story elements and complete gameplay objectives are given a stronger emphasis than in the previous game.
