Most of our current map was pretty difficult to build on. Varied terrain like the Aeklast is wonderful but flatlands is needed to be able to build- that and sources of water. As a faction leader, I can't say how many times I didn't want to settle somewhere because I couldn't justify it without the river or lake. I guess that's probably me being picky on the last part though.
Keep it wild and abstract but make the biomes bigger than they were in the Aeklast. It was so small and each biome could really only have maybe 1 player region in it, or 2 very small ones. But that's because it was less than 1/3 of the map at the time. If the full map is in the style, that'd be wonderful!
EDIT: Also yeah rivers and ponds/lakes for making life feasible.
Well, now that's confirmed by a staff member and not me, I'll explain what I'm attempting ^^
Basically, primary biomes and secondary biomes.
The primary biomes are larger more standard biomes while the secondary biomes are smaller, more specialised biomes~
There's some crossover where a secondary compliments a primary but hopefully the geography makes a little sense. It's probably the loosest I've been with logic.
