Time and Time again - a Strategy game

It all takes place on a board, where you have some zones, or tiles. On each zone you can have settlements, and the zone be one of many types: woods, plains, water, swamp, barren. Zone types affect food production and unit movement speed. The Settlements are simulated realistically, but simplified, with food production, happiness, sanitation, taxation, etc. As a ruler you can adjust food rationing, taxation levels, and choose to construct improvements to make your settlement better. You can also interact with other nations, fight them, or trade, perhaps buy some nice products which would make your citizens happier (so you can tax them even further!)
