What will we do if we have many players around the world and the ping will affect the quality of the game?

To minimize the impact of high ping on game quality with a large number of players worldwide, several approaches are used:

• Geo-distributed servers: Hosting game servers in different regions so players connect to the nearest server with minimal latency.
• Replication and synchronization: Using state synchronization technologies between servers to ensure game consistency.
• Local predictive logic: The client-side of the game can predict actions of other players to smooth out delays.
• Network protocol optimization: Using UDP with minimal latency, data compression, and minimizing the amount of transmitted information.
• Adaptive quality: Adjusting game quality based on current network conditions (e.g., reducing update frequency).

Example: in Golang, a load balancer can be implemented to direct players to the nearest server based on geolocation or ping.
