## Prompt

```text
Build a complete, polished, playable browser clone of Age of Empires II. Capture the experience of growing a medieval settlement, developing its economy, advancing through ages, building an army and defeating a computer-controlled rival. Make the implementation decisions yourself. Prioritize an enjoyable game, strong visual presentation and systems that work together. Test it yourself before finishing, and leave it running so I can play it.
```
