I copied this from the Genre and Setting thread since I wanted to discuss the map components.
First off I am totally opposed to a Pangaea world. I can't imagine it offering a great deal of interesting mapping ideas. Interesting mapping points is what I'm really looking for, this is a fantasy setting in a fantasy world, there is no need to be timid and conservative with the map. Realism should not necessarily be our main concern regarding land forms.
Regarding the World map, I'm happy with editing elements into a map as suggested in two, I mangled my attempt to work on Azelor's map in doing so but it's worth the attempts. Personally I feel like having the whole world map at least in overview is important to starting off. Specifics should be left open for now.
My views on the division are pretty clear. Land modified zones with good buffers. Tying into the next point...
I think the diversity of a world is best served by having a supposed patchwork. Even in this earth I can't imagine mapping cultural boundaries very definitively. I think rather if we have our setting overview and general ideas of what is in the area that is more than enough to run with. Collective decisions regarding these things would lead to an unnecessary homogeneity, and I feel would lead to exactly the opposite of a world that is interesting to read about or play in. It would be far less credible I think than having the greater diversity and creativity a more open plan would allow.
Perhaps if number 2 was done on a more regional scale somehow it would work, but on a world scale I don't think so. Another reason I don't like this is because I want us to be mapping and developing all over the place, not just one region or continent at a time, and doing this while also trying to stick to number 2 is not conducive to one another.
