Map Roleplay Maker

Map Roleplay Maker is a simulation program designed for players to create worlds, simulate them, and use them for external role-playing purposes. 
Use maps for games outside of the program, or simply watch the world develop over time, and make your own manually or from height-maps.
Rather than simulating each pixel constantly, you can set how long you want to simulate and have the whole world move forward. Design maps, customize nations, and use a variety of species to spice up your own world!
