Planet Futanari revival

I've been thinking about this for a few days now. Its like the stories from a few years ago and i'd like to do something similar.

As in the original thread, theres a planet out there thats 4 or 5 times the size of Earth, where evolution occured a little differently. Theres men, women and Futa's. there's many different continents with their own civiliations. i.e more technically advanced than others, others are pretty much jungle areas, deserts, others are still in the dark ages etc.

there'd only be 1 rule, if theres a conflict in your story that involves another writers characters please talk to the writer so any plot lines can incorperate that instead of having whats developed shoved off to the side
