Race Kings port-mortem
summary
GameSparks implements a lightweight real-time backend for Hutch’s Race Kings that uses ordered UDP (drops late/out-of-order packets) to cut bandwidth versus TCP (roughly 60% smaller packets), region-aware matchmaking and server-authoritative clusters so packets can be intercepted for cheat detection, and on-demand real-time instances that scale to hundreds of thousands of users. Packet format is simple — opcode + delivery intent + JSON payload — and the system is already used in shipping titles (MMX, Strikers Edge) and proves to work in production.
