Otaku no Seiza is a Japanese-style role-playing game with humorous overtones. The gameplay system follows the Dragon Quest template: the player controls the hero and his companions as they navigate through a top-down world map, visiting towns and dungeons, and engaging in first-person turn-based battles against randomly appearing enemies. Characters can execute special attacks called "Force". Leveling up is automatic, and interaction with characters and the environment requires selecting "Talk" and "Search" commands from a menu.
