// the problem

Challenge

Building a real-time 4X strategy game requires sophisticated physics simulation for orbital mechanics, deterministic combat resolution, efficient state synchronization for multiplayer, and AI opponents with distinct personalities. The technical complexity is comparable to MMO infrastructure.

// what we built

Solution

Space Game uses PixiJS for 2D rendering with a custom physics engine for orbital mechanics. Combat uses deterministic calculations for fair multiplayer. WebSocket connections with efficient state synchronization minimize bandwidth. Multiple AI personalities provide varied opposition with distinct strategic approaches.
