The primary goal is to route users to the game servers with the optimal response time, which is determined by network latency. Amazon Route 53's latency-based routing policy is specifically designed for this use case. It directs traffic to the AWS Region that provides the lowest network latency for the end user. Route 53 determines the lowest latency region by using a continuously updated database of latency measurements from various parts of the internet to each AWS Region. This ensures that each user is connected to the server that will provide the most responsive gameplay experience, directly addressing the reported problem.

A. Weighted routing distributes traffic based on predefined static ratios, not on real-time user latency, and would not optimize individual user response times.

C. Multivalue answer routing returns multiple records to the client, which does not inherently guarantee a connection to the lowest latency endpoint.

D. Geolocation routing uses the user's geographic origin, which is an approximation for latency but is less precise than direct latency-based measurements.

1. AWS Documentation, Amazon Route 53 Developer Guide: "Latency-based routing lets you route your traffic to the AWS Region that provides the lowest latency... When Route 53 receives a query for your domain... it checks its latency records and determines which AWS Region you're serving your content from that has the lowest latency for that resolver's network." (See section: "Choosing a routing policy," subsection: "Latency-based routing").

2. AWS Documentation, What Is Amazon Route 53?: "Latency-based routing – When your application is hosted in multiple AWS Regions, you can use latency-based routing to route users to the Region that provides the lowest latency." (See section: "How Amazon Route 53 routes traffic for your domains").

3. AWS Whitepaper, Amazon Route 53 and DNS (Page 11): "Latency-based routing policy – Use when you have resources in multiple AWS Regions and you want to route traffic to the Region that provides the best latency." (See section: "Routing Policies").
