Multiplayer game backends typically lose player state when a server crashes because state lives in memory tied to a specific server. Temporal's Actor Workflow pattern solves this by modeling each player as a durable, independently-running Workflow identified by their player ID. Each Workflow holds inventory, health, position, and room state in memory and drives game actions (joining rooms, combat, leaderboard updates) through Activities. When a server goes down, the Workflow resumes on another Worker from exactly where it left off — no state lost, no reconnection logic needed. Long-running sessions are handled cleanly via Continue-As-New to avoid unbounded history accumulation.
