Adam Bosarge, Kyle Simons and Jason Faulk have launched their Kickstarter campaign for Worlds in Peril, a Superhero RPG based on the Apocalypse World engine. They look to be doing some interesting things with damage conditions and building characters from multiple mini-playbooks that represent their origin and drive/motivation (e.g. ‘See justice done’), plus I’ve been waiting for a *World game that cracks the superhero genre for a while. This is a strong candidate.
The Kickstarter campaign finishes on 12 May 2014.
