About This Game

The First Sino-Japanese War is a free and open-source game simulating the namesake conflict of 1894–1895. The game includes a naval tactical combat system that uses a dynamic time step (e.g., 1 second per pulse) but is generally played in 1-minute turns. Its core resolution mechanics are inspired by the famous miniature naval wargame SEEKRIEG 5, while gameplay is influenced by Rule the Wave (1-minute turn flow), JTS Naval Campaigns (aesthetics), and Command: Modern Operations (runtime editor).

The strategic layer (still under development) uses 1-day turns, 50 km/hex and a WEGO system. It covers tactical naval combat generation, strategic-level land combat resolution, supply, and political simulation.

Steam does not allow hyperlinks in descriptions, so please use the “Visit the Website” button to access the GitHub source repository. The game may release a pure donation-based DLC to help cover some costs.
