It’s a tie. The folks at Evil Hat did a multi-book Kickstarter that included the Atomic Robo RPG. It was well-run, successful, got the books out on time, and kept the backers informed every step of the way. Similarly, the Transhuman Kickstarter by Posthuman Studios for the Eclipse Phase game was excellent on communication, delivered slightly ahead of time, and had been continuing to pump out their stretch goals on time.

I would also throw in a big shout out for Dr. Dante Lauretta and the people at Xtronaut Games for their superb Kickstarters for Xtronaut and the soon-to-ship Constellations board games. Lauretta is a project manager, I believe with the OSIRIS-Rex mission, and both campaigns were absolute exemplars of how to do Kickstarter. The games are also superb and I highly recommend them.
