I just really like the layout of a design that seems feasable in the real world...like that map that had the lower left-corner (about 1/8 of the map) which was a long-stretching diagnol Mesa, and it was bordered down-low by swamps. There were also nice mountain chains that seemed to flow from flat-ground to high-ground to hills to chains of mountains. It just had such a nice, natural (ie, possible) feel to it.
Some maps I make (by messing with sliders) end up having one huge single mountain, forest next to it, swamp, then forest, then 3 mountains, then water, then forest. There is no "feel" to the continuity of it, which is what I would love to shoot for in each map.
Still, this is a very good tool. I am just hoping to get better, and hoping some revisions come to help with the "natural" feel of worlds.
(so in other words, thanks a lot for your effort so far, and I plan to keep trying and using this baby! )
