generating maps

[Makinus]

I wish to generate a random map witha higher proportion of deserts and tundra (higher tham setting the map caracteristics to arid and cool), how i can do this?

I also want to generate a random map with a more archipelago like setting (the archipelago setting of the editor/civ3 is to "continental" for my tastes), is this possible?

Thanks.

Once you have used teh max settign for water/land and age/wet, you will have to use the terrain tool to add/remove land and to turn more land into desert AFAIK.
