Indeed. Actually my biggest problem is I see requests based onthe results of the generator on big maps and my comp can't handle more than normal for playing, so I don't test bigger than normal maps, except an occasional large map, but even these take very long to displlay in the world builder. The advantage of fractal maps is you don't really worry about map size, things will scale smoothlessly because it's fractal. Adding more hills by an additional pass of plate movement and some erosion coould provide for more hills, maybe some isolated ones, but on small or medium maps I think it's not useful.It is an interesting twist in two opposite directions to see requests for both more realism and for less, to improve the results.
The climate could need some work too, since it's very "straight" lines, but here I strike a realism/gameplay problem.
I have unfortunately lost the 3.1 version in which I had created a set of plates to generate Earth continents just to see what it looked like and to help get more realistic results. Of course it showed that my script is not tectonically correct at all, but it helped in getting subduction right and showed some interest for climate with the Sahara in particular.
