Claude Opus 5.5 built an Age of Sail strategy game.

The entire project was made with Opus 5.5 using Blender + Roblox Studio -- ships, animations, sounds, sailors and gameplay systems.

Around 4,600 sailors are simulated, with ships adjusting sails, pulling ropes and preparing for combat.

The creator is even running massive 30v30 ship battles.

AI game development is moving fast.
