The Multiverse RPG is a super wide background setting for basically any campaign. It's presented first because all other settings can be used as a part of a multiverse campaign.
When I first wrote this setting, I also wrote yet another system. I recently rediscovered it, and still found it interesting, so here it is.
Metahuman Far Future is a travelleresque future, but with a more contemporary feel. This is a bit of an "umbrella setting", too. You can fit a great many worlds under this meta setting.
The Planet of everything is a cyberpunkish backdrop for a character developement campaign I've been designing. The characters start out as street punks and little by little rise in power. Eventually the game may "break out" into a Metahuman far future or even a multiverse game.
