You could really freak it out with the Ter2Blend script,…but of course you would need to install Python 2.2 and terragen. 
Also there is S68s ‘World Forge’ which I have yet to try, but looks waaaaay cool. Anyway, Terragen is not that hard. MUCH simpler than Blender.<edit> check it out, here is a sampling of me fooling with the ter2blend script==>
