You'll have to do some experimentation to get the settings right for your tastes, and you'll probably create some truly horrible maps in the meantime, but its well worth persevering. I tend to use the worldbuilder to check out the first few maps (using regens) to see if the script I've chosen is providing the kind of map I'm after, and then play a new regen once I'm sure (and write down the settings for future use). Read surt's "options" section before you start, so you know (roughly) what each of the settings does.
