A Japanese solo developer has created "Jyoka -Castle town-"—a real-time strategy (RTS) and castle-town construction game set in 16th-century Japan—following a three-year development period. The game’s store page has now gone live, and its release date has been announced. It is already garnering significant attention, having accumulated thousands of wishlist additions just days after the store page’s launch.
"Jyoka" Launch Trailer
Set in 16th-century Japan—an era defined by the samurai—this "castle town-building and strategy" game casts the player as a minor local lord. The gameplay unfolds in three distinct phases: developing a castle town, defending it against invasions from neighboring territories, and—once the realm is stabilized—striving to unify the entire country.
--------------------------------------------------
Key Features:
--------------------------------------------------
- Feature 1:
This game blends three distinct phases: the early stage focuses on developing a castle town to build national wealth (city-building); the mid-stage adds the challenge of defending against other nations (strategy); and the final stage involves attacking other territories to expand your domain (simulation).
(By adjusting the difficulty settings, it is also possible to focus exclusively on city-building.)
- Feature 2:
You can begin the game by selecting any location on the map of Japan as the hub for your town-building efforts.
(Note: You cannot choose the sites of enemy castles—located across the 73 provinces of Japan—or extremely small, isolated islands.)
- Feature 3:
There are over 190 types of buildings that can be constructed, and 73 actual, extant castles that can be besieged.
Please check the Steam store page for further details, and consider adding the game to your wishlist.
