Will terrain generation always use the autogenerating method it does now as opposed to say pre-designed maps of a set size?
The reason I ask is because it would be nice to be able to create maps a certain way with features where I want them. It would also make the terrain more realistic rather than just a huge expanse with random features dotted around - could actually have continents and islands and realistic geography 
I love this idea! I would love to explore maps based on fictional worlds. Of course it would be nice to have a world border/invisible barrier so you don't generate new random terrain.
Take a look at this: Customisable or better Predefined World Generation
This too: New World Settings
Wow! there are so many pages of suggestions. So, I'm going to add mine here.
Can we have a few "seeds" set aside for the creation of specific worlds? I.e. The Earth, or if that's to big than one for say Africa, another for Eur-Asia, etc. And also like Nirn(Elder Scrolls), The Game of Thrones word(Westeros ??), etc.
I have a height map for Tamriel I found on Nexus Mods, could I use it to start the creation of my own Map seed?
