I’ve put my own two offerings forward for bySwarm’s rpg setting contest. Put up your own ideas here, and be sure to read up on mine and rate them. (username Robosnake)
What they’re doing over at bySwarm is working on an experiment in collective setting design. Right now people like myself with too much free time are posting setting theme documents for consideration. At some point they’ll select something, by popular vote it looks like, to expand upon and to attach to an rpg system.
Anyway, it looks interesting. Right now there don’t seem to be that many posts, but it is cool to get in on or near the ‘ground floor’ in something like this.
