Ambitious indeed.

Qs.

What format are you storing your graphics files in?

I notice all your examples are square. Is that the current field of your algorithms?

What programming language(s) are you using?

Have you thought about working through individual aspects separately? If so, do you have a part of the process you're working on right now? You know, if the interesting bit is the world making. You might be able to make some cool filters for the Gimp or Photoshop. You'd be spared from doing the rest of the interface.

Can you generate your rivers on a separate layer and then apply only localized erosion around the rivers to preserve the rest of your map? Or offer a sliding scale to the user starting with the rivers and proceeding with the rest of the erosion?

Good luck
