Design a real-time multiplayer online game that supports a large number of concurrent players. The game should provide an engaging and immersive experience with low latency and high responsiveness. Consider factors such as game mechanics, networking, server infrastructure, client-server communication, and synchronization in your design. Discuss how you would handle player interactions, game state management, and cheating prevention. Additionally, address scalability, fault tolerance, and load balancing to accommodate varying player loads and ensure a seamless gaming experience. Provide insights into the technologies, protocols, and architectural patterns you would employ to build and deploy this real-time multiplayer online game effectively.
