Romancing SaGa
Romancing SaGa is a role-playing video game where the player takes on the role of eight different protagonists, playing through their narratives and an overarching story in a nonlinear style. After choosing a protagonist, the player explores the game's overworld freely, triggering narrative events, engaging in battles, and performing side activities. Over the course of the game a party of characters is built up, with some recruitable members being the unchosen protagonists. Progression of the main narrative is based on the number of events the player completes, their current strength, and speaking to certain characters. This free exploration is dubbed the Free Scenario System.
