Four Crossings of the ChiShui River Simulator

As an individual developer, during development of this game, AI tools were heavily used. I disclose this honestly and transparently.

1. In-Game Assets

Illustrations & Art: Unit portraits and the opening cinematic illustrations were generated using AI image models, then manually curated, retouched, and unified in style. All assets were human-reviewed under strict art direction to ensure historical tone and consistency.

Opening Cinematic: Subtle motion effects on the illustrations were produced with an AI image-to-video model and assembled by using the Remotion pipeline.

Background Music: The soundtrack was generated by an AI music model in multiple takes, then human-selected, mixed, and mastered.

Telegram Voice-overs: The historical telegram voice-overs in-game were synthesized by an AI TTS system. Each character's reference voice was human-approved through listening tests before use.

2. Development Assistance

Code: Game code was written and debugged with the aid of AI coding assistants. All code was human-reviewed and validated through automated testing.

Localization: The game supports Simplified Chinese, Traditional Chinese, and English. The English text was AI-drafted and human-proofread.

3. What Is NOT AI-Generated

Historical Text: The telegrams in-game are taken from historical archives, 34 are verbatim transcriptions of the original documents, and 12 were written based on the sources. They were not AI-generated.

Terrain & Map: The battlefield map was procedurally rendered from real elevation data (SRTM), not generated by AI.

Game Balance & Statistics: Troop strength, Unit Introduction, and values were researched and set manually from historical sources, cross-checked for accuracy and play balance.
