Live events are useful for player retention and driving key metrics like logins, play time, spending, and engagement. They also provide short-term goals, highlight game content, foster community, and create a shared history. To deliver successful live events, developers need to balance predictability and surprise. Live event teams should have a process focused on goal setting, data collection, analysis, and iteration to continually improve events. Common live event types include login events, game modes, drop events, tournaments, and goal events, each with different purposes and best practices.
