Thanks Rust
I never really had much experience role-playing in or writing for a sci-fi world. The concept is to make it primarily for a fantasy world, but if I can do it right, the Green should be a good place to drop into for an adventure or two for any kind of setting with a little adjustment. Space ships or gate-crashers could bop in for an adventure or two and then go to some other wild planet or setting people are writing up. I plan on writing up specific tree and swamp magic stuff and that may be a little trouble for some more realistic sci-fi adventures, but hopefully that can be left out if a GM chooses.
If this thing really goes off it might be handy to write a page or two appendixes to each world explaining how they could be adapted to other peoples creations. That would be good fun.
On a different note your water world sounds really cool, but the post is tantalizingly brief. It seems like you have a lot of ideas you can go with. Do people/ other races breathe water or do they need devices? Are you going to have underwater vehicle rules? Underwater combat rules? Do people live in domes, caves or something else? What kind of weapons do they use underwater? Like the big tree concept, many movies, books, and comics have toyed with this thing, but to my knowledge it has never been truly explored in a unique game world. Good luck, I am looking forward to reading more about it.
