Can you make it larger then 2km? or is it a max limit? srr too many questions.

I absolutely love this map. Plenty of flat spaces with cliffs to make castles with epic vistas. I have a couple of ideas you gould use.

Archipelago - chain of islands (surrounded by dirt since there's not water yet) maybe with some high cliffs.
Island - Kinda the same as the previous but instead a single large island with high cliffs.
Fjords - High cliffs with deep canyons in between. The canyons should be 90 degree directions to make proper bridges over.
Greek Island - Find some greek island and see what looks best :p
Just thought any of these would look awesome :D

@Caedes whats unique about them, I dont realy know anything about them.

very cool looking. Nice work. Keep it up.

Wow! Have you considered doing something resembling the Appalachian Mountain Range?

i like this craggy look, it actually reminds me a bit of karst areas or mountains like the dolomites in europe. maybe because of the rockcolor.
interessting without trees, maybe a bit hard if full survival kicks in ;)

as an idea, something like this, but not as high, more like plateaus divided by steep ravines and eroded sidecliffs where they meet the flatter terrain.

Have an idea for a map? let me know
