A free browser game from Core Systems Asset Factory. Genre: Simulation, Strategy. Free.
FLOODMARK is a free browser game, free to play in the browser.
Every spring the river comes up over the valley. You do not stop it. You aim it. Silt from the floodwater is the only fertility your fields will ever get. A field the water reaches gains silt and yields that much grain the same year. A field the water misses loses a point every year to exhaustion, until it is bare dirt.
Reedbeds and clay pits are worse: in a year the river does not reach them, they yield nothing at all. But everything you build hates the water. Houses, granaries, mills, bakeries and kilns are silted up for a year if the river gets to them, and lost outright in deep water. So a perfectly walled town starves, and an unwalled one drowns. The best wall is a leaky one, and deciding where it leaks is the whole game.
The year has four steps and none of them is a timer BUILD → CALL THE RIVER → THE HARVEST IS COUNTED → THE COUNCIL MEETS. No clocks. No energy bar. No waiting for a barn to fill while you go and do something else. The year advances when you say so, and the pressure comes from a system you aim rather than one you wait out. A run is twelve to thirty-five years, call it ten minutes.
