Based on a system designed by Henry Hyde and published in Battlegames magazine
, this terrain generator will randomly generate a grid of squares in the size you specify, each marked with the dominant terrain type for that square. From this grid, you can work to create a map of your fictional lands. I highly recommend acquiring Battlegames issues 3,4, and 5 in order to see the rest of Henry's system at work, allowing you to establish rivers and cities and generate population and revenue figures for your fictional country or region. Henry's system is used with his gracious permission.
