Your Fantasy Toolkit Supersetting
From the introduction:
RPGS, or RPG Supersetting, is a system-neutral fantasy roleplaying setting, free to download, easy to use, and open to your vision. It is a setting with enough details to be run quickly and to be the foundation for a campaign, open to further development. It is a world full of adventures and dangers where heroes are needed. It is a collaborative world and you can be a
part of it!
The project came from a single map on a computer screen and an idea, the desire to create a fantasy setting in collaboration. RPGS is the collective child of several members of the YouTube RPG Brigade, an online community of roleplaying games enthusiasts, and friends of the Québec Wednesday Night Gaming Group.
Each collaborator was asked to roll some dice, to choose some hexes on a empty world map, to answer a bunch of questions and to develop from these basic answers, leaving you with enough space to do whatever you want with these starting points.
