I skimmed through and noticed no one posted the Cortex Plus Hacker's Guide. It'll be essays and guides on tweaking the system for the Smallville RPG, the Leverage RPG, and (most likely) a little bit of the new Marvel Heroic Roleplaying game. If you haven't looked into these games, they're some of the most well-designed ones on the market right now, and infinitely mine-able for good ideas. This project gives you tips, tools, and guidance on how to adjust said systems for even more genres and settings. It's already fully funded, we're just hoping to get into the really juicy Stretch Goals now (Fantasy Heroic Roleplaying and a full rule set for generic Cortex+ Drama)!
