The agent successfully navigates to the 'Game' section of the website. The agent successfully navigates to the 'Leagues' page. The agent accurately explains that a 'League' is a temporary game world with unique challenges, mechanics, and a fresh economy, typically lasting for a few months. The agent states that new Leagues are introduced roughly every three months (or similar phrasing indicating regular, periodic introduction).
