100 Planets+

As a companion to the previously released 100 Science Fiction Adventure Seeds, Postmortem Studios has released 100 Planets on DriveThruRPG. This generic supplement for any science fiction roleplaying game describes (you guessed it) one hundred different worlds, each with a unique geography and society, and several adventure seeds.

If you find this type of publication useful, you might also check out 101 Cargos, 101 Corporations, 101 Governments, 101 Lifeforms, 101 Patrons, 101 Plots, 101 Religions, 101 Rendezvous, 101 Starcrews, and 101 Travellers, all from the British Isles Traveller Support (BITS) organization.
