Riot Games (League of Legends + Valorant live ops)
2010s-present
Riot Games has built one of the most sophisticated live-operations platforms in gaming, supporting hundreds of millions of monthly players across League of Legends, Valorant, Teamfight Tactics, and Wild Rift. The company invests heavily in matchmaking AI, anti-cheat (Vanguard), behavioral systems, and trust-and-safety classifiers โ the latter built on years of player-behavior research. Vanguard's kernel-level anti-cheat in Valorant and the company's behavioral systems work in League are widely cited as industry benchmarks for handling cheating and toxicity at scale.
Lesson
Live-ops at gaming scale is a multi-year platform investment, not a feature. The teams that win at the next launch are the ones that built the observability, anti-cheat, and trust-and-safety capabilities into the platform years before they needed them.
