Persona 3 combines elements of traditional role-playing games and simulation games. The game follows the protagonist character, balancing their daily lives of going to school and building relationships with other people with fighting evil beings known as Shadows during the mysterious Dark Hour. Each day is divided between various time zones, the most common of which are "After School/Daytime" and "Evening." Except for scripted events, such as plot progression or special events, the player is free to choose how each day is spent, with most activities causing time to pass on. The types of activities and characters that can be interacted with vary depending on the day of the week and time of day. Additionally, some activities are limited by the protagonist's three attributes; Academics, Charm, and Courage, which can be built by performing various activities or making certain correct choices.[1][2] During the evening, players can choose to visit Tartarus, the game's main dungeon, where they can build their party's experience and gain new items. On the day of the full moon, players will participate in a boss battle to progress the story.[3]
